You are asked to design a spring that will give a 1080 kg satellite a speed of 2.65 m/s relative to an orbiting space shuttle. Your spring is to give the satellite a maximum acceleration of 5.00g. The spring's mass, the recoil kinetic energy of the shuttle, and changes in gravitational potential energy will all be negligible.

A)What must the force constant of the spring be?

Take the free fall acceleration to be g = 9.80 m/s2 .

b)What distance must the spring be compressed?

A 2000-kg truck is sitting at rest (in neutral) when it is rear-ended by a 1000-kg car going 20m/s .After the collision, the two vehicles stick together.

1)What is the final speed of the car-truck combination?

2)What is the kinetic energy of the two-vehicle system before the collision?

3)What is the kinetic energy of the system after the collision?

4) Based on the results of the previous parts, what can you conclude about which type of collision this is? Elastic, Inelastic, or totally inelastic?

5) Calculate the coefficient of restitution for this collision.

ment advisors recommend risk reduction through international diversification. International investing allows you to take advantage of the potential for growth in foreign economies, particularly in emerging markets. Janice Wong is considering investment in either Europe or Asia. She has studied these markets and believes that both markets will be influenced by the U.S. economy, which has a 19% chance for being good, a 48% chance for being fair, and a 33% chance for being poor. Probability distributions of the returns for these markets are given in the accompanying table.

a. Find the expected value and the standard deviation of returns in Europe and Asia. (Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.)

b. What will Janice pick as an investment if she is risk neutral?

• Investment in Europe

• Investment in Asia

In a paragraph or two, note an additional point that might be added to the five that are listed. Base your response on what you’ve learned from the course—using any chapter from the book as the basis for your additional point. Be sure to support your point with the reason that you’ve added it to the list of five—how is it relevant?

1. a. Define the terms “Marginal Revenue” and “Marginal Cost”.

     b. Illustrate and explain in detailhow a perfectly competitive firm uses MR and

         MC to identify its profit-maximizing output.

     c. Once a firm has identified its profit-maximizing output, will the firm necessarily

         be earning economic profit at that output? Explain in detail.

     d. Explain how a firm uses Average Revenue and Average Total Cost to determine

         the level of profit that it earns.

     e. Is it possible for a firm to incur economic losses while producing its profit-

        maximizing output? Explain.

Capacitors won't hold a charge indefinitely; as time goes on, charge gradually migrates from the positive to the negative plate. We can model this as a discharge of the capacitor through an internal "leakage resistance." A 0.49F capacitor charged to 3.7V will initially discharge with a leakage current of 0.25mA .

I found the leakage resistance to be 1.5

Prove that for any t > 0  x_i(tp,tw) = x_i(p.w), i.e. that if all prices are multiplied by the same positive number the factor inputs that maximize profits will not change, or that the factor demand functions are homogeneous of degree zero.

Question 1 for strings

a) Write a function named longest_common_prefix that takes two strings and returns the longest common prefix of the two strings. For example, the longest common prefix of distance and disinfection is dis. If the two strings have no common longest common prefix, the method returns an empty string.

b) Write a function named reverse that takes a string argument and returns its reverse. For example, reverse(‘I am testing’) should return the string ‘gnitset ma I’. Use iteration for this and answers using slicing will not be accepted. Imma like... what.

c) Write a function named check_password that checks whether a string is a valid password. Return True if it is a valid password and False otherwise. The password rules are as follows:

• A password must have at least 8 characters.

• A password must consist of only letters and digits.

• A password must contain at least two digits.

Two dice are thrown.

Let A be the event that an odd number is obtained on the first dice, B be the event that the number obtained is greater than 5 on the first dice, C be the event that the number obtained on the second dice is smaller than 5, and D be the event that the sum of the two numbers obtained is 8.

State whether each of the following is a pair of independent events or dependent events.

(a) A and B

(b) A and C

(c) B and D

(d) C and D
