You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.73 s, and the velocity of the car decreases to + 5.37 m/s. The car’s deceleration has a magnitude of 3.02 m/s2 during this time. What is the car’s displacement? x =

A dynamite blast at a quarry launches a rock straight upward, and 1.8 s later it is rising at a rate of 10 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 4.4 s after launch.

Concept Simulation 2.3 provides some background for this problem. A ball is thrown vertically upward, which is the positive direction. A little later it returns to its point of release. The ball is in the air for a total time of 8.36 s. What is its initial velocity? Neglect air resistance. v0 =

Concept Simulation 2.3 offers a useful review of the concepts central to this problem. An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +21.2 m/s and measures a time of 18.4 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (positive = up, negative = down)

A hot-air balloon is rising upward with a constant speed of 3.78 m/s. When the balloon is 9.24 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground? From her bedroom window a girl drops a water-filled balloon to the ground, 8.93 m below. If the balloon is released from rest, how long is it in the air?

Describe the path a red blood cell takes traveling through the body. Begin your RBC in the right atrium and show its path until it returns to the right atrium. There should be at least 7 steps, but could be more depending on how detailed you get.  

A “friend” borrows your favorite compass and paints the entire needle red. You discover this when you are lost in a cave and have with you two flashlights, a few meters of wire, and (of course) your physics textbook. How might you discover which end of your compass needle is the north-seeking end?

1) Define what is behavioral finance.

2) What's the difference between classical finance and behavioral finance

3) Explain what is anomaly in finance, and state two examples of annomaly

3. It is sometimes said that a balance of trade deficit between the United States and other nations can be harmful to the economic wellbeing of America. Explain what is the “balance of trade.” What does a “trade deficit” or a “trade surplus” mean? Why do some people say a trade deficit is “bad” and a trade surplus is “good”?

Many economists reply to these arguments that, at the end of the day, it does no “harm” for a country to run a trade deficit, certainly it does not matter with any particular country, and nor does it matter when looking at the U.S. and all of its trading partners as a whole. Explain in detail the logic of their argument. After explaining these two point-of-view which do you think in more correct? Why?

Consider a high-speed subsonic wind tunnel. The conditions in the large-diameter section upstream of the test section are V = 228 mph and T = 540°R. At the test section, the temperature is 473°R and the pressure is 2 atm. (a) If a wind tunnel model, placed in the test section, has a wing chord of 12 in., what is the test Reynolds number based on that chord? (b) What is the overall smooth flat-plate skin friction coefficient of the model wing if the boundary later is turbulent? (c) Determine the boundary layer thickness at the trailing edge of the model wing. (d) Calculate the skin friction drag in pounds for a model with a span of 3 ft.

Bold Bodybuilders, Inc. is a large sporting goods store. It has become the exclusive distributor of the new bodybuilding equipment called Geni. After carrying the equipment for a year, Joe Sabatini, a manager of the supply chain, decided to analyze the company's inventory policy for Geni. On the basis of the past year's record, Joe has identified the following weekly demand data:

Weekly Demand Occurrence, Week

95 8

96 2

97 6

98 10

99 8

100 6

101 6

102 2

103 4

Total 52

The annual demand for Geni is considered to be 5,128 units, annual holding cost per equipment is $244, and ordering cost is $4,250 per order. The equipment price is $929 per unit. The new order is made when the inventory level in the store drops to a predetermined number of units on hand. Once the company orders Geni from the supplier, it will come to the store in about 3 weeks.

Questions (Please fill in your answer using the enclosed Excel answer template)

1. Explain what inventory planning and ordering system you are going to use in this case and why.
2. Identify the optimal order quantity and total annual inventory cost. Explain the insights of your results.
3. What are the best safety stock and reorder point that guarantees with a probability of 99% that the store will not run out of stock of Geni equipment? Explain the insights of your results.

Find an article about the misuse of statistics and share what you have learned from the article. Then, find an example of when statistics were misused/skewed and state the reason why you think the statistics were reported that way.
