1. For any good that could potentially be provided by a private firm, the degree of rivalness can be measured by the rivalness ratio SMC/AC. a.[5] How must SMC be defined in order for this rivalness ratio to be able to measure the rivalness of goods that are purely private and also goods that are shareable and nearly purely public? Explain. b.[7] Describe two different benefits of using the rivalness ratio instead of using the SMC of a good to measure the rivalness of that good. c.[5] What is the most likely reason that during a typical three year period the private marginal cost of electricity production fueled by burning coal averages about half of the average cost? d.[12] Use information from the N4 notes, from class and from part c to give your best estimate of the rivalness ratio of each of the following goods. Justify your estimate and explain why it uses the definition of SMC you gave in part a: (d1) an iPhone X during the year that started on February 20, 2017 (about half a year before commercial production of the iPhone X started) and ended on Feb. 20, 2018; (d2) an ebook during a one year period starting 2 months before it can first be downloaded; (d3) electricity produced by burning coal in the US during a 3 year period.

POTENTIAL AND KINETIC ENERGY

OBJECTIVES:

  1. To determine the potential and kinetic energy of a freely falling body
  2. To determine the loss in kinetic energy of an inelastic collision
  3. To calculate the percentage error of the experimental error of the velocity of a freely falling body using the conservation of mechanical energy of a body

MATERIALS:

  1. Tennis balls
  2. Digital Timer
  3. Meter stick

THEORY:

  1. Conservation of Mechanical Energy
  • A body raised to a certain height possesses potential energy due to its position. Since work was done to lift the body to a certain height, the body gains potential energy. When the body is released from its position, the potential energy is transformed into kinetic energy on its way down. Upon reaching the ground, the potential energy is converted into kinetic energy. Ideally, if there is no loss in kinetic energy, the body should bounce back to its original height. This only happens for a perfectly elastic collision
  1. Inelastic Collision
  • In most situations however, once the body reaches the ground, some of its kinetic energy is lost (e.g., the body undergoes slight deformation upon collision with the ground). The body will then reach a lower maximum height than the original height from which it was dropped. Eventually, the body will lose all its kinetic energy and will rest on the ground once all of its kinetic energy is lost. In this case, the collision is inelastic; that is, kinetic energy is not conserved.

Procedural Instructions:

  1. Decide as a group the original height from which the ball will be dropped. Record this in your data table. After the ball bounces up twice, record also the maximum height reached by the ball for each bounce. Assign one member to note these two maximum heights.
  2. Assign three members to record the time for the ball to reach the ground from its original height, first maximum height, and second maximum height. Note that three members would be needed to measure these different times. Record these in your data table.
  3. Complete your data table to find for the velocity of the ball each time it reaches the ground. You are responsible for the equation that should be used. Using the times and the corresponding heights you have recorded, discuss as a group the appropriate formula to be used and apply them. Record your results in your data table.
  4. Using your equations for kinetic and potential energies, again, discuss as a group the appropriate formula for determining the theoretical value of each velocity you have computed and apply it. Record your results in your data table.
  5. Compute for the percentage error for each velocity.

QUESTIONS AND PROBLEMS:

  1. What is the percentage error on each of the velocities in your experiment? Discuss with your members what could have caused this error.
  2. How is the loss in the kinetic energy manifested by the ball each time it reaches the ground?
  3. In your experiment, calculate the kinetic and potential energies when the ball was on its midway down the first, the second, and the third time. What can you conclude about the total mechanical energy of the ball as its falls down the ground?

A report States that the cost of repairing a hybrid vehicle is falling even while typical repairs on conventional vehicles are getting more expensive. The most common hybrid repaired replacing the hybrid Inverter assembly had a mean repair cost of 3927 in 2012. Industry experts suspect that the cause will continue to decrease given the increase in a number of technicians who have gained expertise on fixing gas electric engines in recent months. Suppose a sample of 100 hybrid inverter assembly repairs completed in the last month was selected. The sample mean repair cost was $3780 with a sample standard deviation of $600. Complete parts A and B below.

a. is there evidence that the population mean cost is less than $3,927? (use a 0.05 level of significance)

Jerome claims to have injured himself as a result of falling from the icy stairs of...

Jerome claims to have injured himself as a result of falling from the icy stairs of Tabaret hall due to snow being not properly removed after early snowfall and low temperatures in mid-November in Ottawa. As a result of the bad fall, Jerome will not be able to work for a while and will need to undergo surgery to repair a broken hip. Jerome, upon suggestion of his private insurance, is suing the subcontractor in charge of snow removal for negligence because, despite the snowfall was predicted by the weather forecast several days in advance, no shoveling or salting took place for two days after the first snowfall. Jerome is asking for damages of $1.5 million considering both the loss of working days, the decreased quality of life, and the high costs of surgery/hip replacement. As a result of some initial negotiation Jerome offered to accept a settlement of $750 thousand. Snowclear, the snow removal contractor, thus has a few options: One is to accept the settlement and pay Jerome the agreed $750 thousand. Snowclear lawyers are also suggesting an alternative approach consisting in a counter-offer of $400 thousand in the hopes he will accept a lesser sum in order to avoid lengthy and costly process of a full-fledged trial.

However, Jerome strongly believes in his case and might still decide to refuse the counter-offer and let the judge and jury decide the proper sum to be paid (if any) by Snowclear during a trial. More specifically, Jerome can react in one of three ways: (1) accept the counteroffer of $400 thousand, (2) reject the counteroffer and take the case to court for a full trial where jury will decide, (3) Jerome himself will make a counteroffer of $600 thousand for settlement. If (3) happens then it will be Snowclear’s call on whether to accept such counteroffer and pay Jerome the $600 thousand or go to trial. If the case goes to trial there are three possible outcomes: (1) the jury may reject Jerome’s claim and Snowclear will owe nothing, (2) the jury will award Jerome the $750 thousand agreed upon during initial negotiation between the parties, (3) the jury will conclude that Jerome has a strong case and sentence Snowclear to pay him the full $1.5 million Jerome initially requested.

Key considerations when preparing Snowclear’s strategy on how to handle the situation are the probabilities associated with Jerome’s response to the counteroffer of $400 thousand, and the probabilities associated with the three possible outcomes for the trial. Based on historical cases similar to Jerome’s, Snowclear’s lawyers estimated that he will accept the counteroffer of $400 thousand with a probability of 0.10, that the probability of Jerome rejecting the counteroffer of $400 thousand is 0.40, and that the probability of Jerome himself making a counteroffer of $600 thousand is 0.50. If the case goes to trial they believe that the jury will award Jerome the full damage of $1.5 million is 0.30, the probability that the jury will award Jerome $750 thousand is 0.50, and the probability that the jury will award Jerome nothing is 0.20.

Perform an analysis of the problem facing Snowclear and its legal department and prepare a report that summarizes your analyses and final recommendations. Please include:

1. A decision tree modeling the problem

2. A recommendation on whether to accept Jerome’s initial offer of settlement for $750 thousand

3. A decision strategy that Snowclear should adopt if they decide to go ahead with their counteroffer of $400 thousand
