1. A ball is at rest on the top of a hill (see the figure).
At the top of the hill, the ball will have [the maximum value of its, no, the minimum value of its] gravitational potential energy and [no, the maximum value of its] kinetic energy. If the ball rolls down the hill then, its [gravitational potential energy, kinetic energy] is converted to [gravitational potential energy, kinetic energy] when it gets to the ground.

2. Get your stopwatch ready and prepare to drop the object from the height h you selected in the previous step. You should drop the object so its [bottom, top, middle] part is initially at the height h. The initial speed of the ball [zero, 9.8 m/s, 9.8 m/s^2, depends on the height h] You'll need to measure the time from when the ball leaves your hand to exactly when it hits the ground [ for the first time it bounces, after it bounces and then comes to rest, both the first time and then after it bounces; then average the two times]

Like your competitors in the pool service business, you provide pool service 4 times per month but invoice customers for service on a monthly basis. When you raised the monthly price of pool service from $125 to $140, you lost 28 customers, leaving you with 90 pools to service. You believe that your demand curve has constant elasticity and has not shifted since you started your business. a. Estimate your elasticity of demand? b. Given the cost of pool chemicals, gas, wear and tear on your truck and your time, you believe that the marginal cost of servicing an additional pool in East Dallas is $75 per month. What can you say about your optimal price? Was it a good idea to increase your price? Over time, you realize that half of your 90 customers appear to be more price sensitive than the other half. You know that your customers communicate with each other and would be unhappy knowing that they are paying different prices for the same service. However, in talking with your price sensitive customers, it is clear that they would consider paying for less frequent service if the price were right. In fact, your less price sensitive customers would be willing to pay $190 per month for the current ( 4 times per month) service and $150 per month for reduced service ( 3 times per month). The more price sensitive customers are only willing to pay the current price of $145 per month for the current ( 4 times per month) service, but would be willing to pay $120 per month for reduced ( 3 times per month) service. The marginal cost of current ( 4 times per month) service remains $75 per month, while the marginal cost of the reduced ( 3 per month) service package is $60 per month. c. What type of price discrimination are you considering engaging in? Explain your answer. d. What is your incentive constraint? e. What is your optimal pricing strategy and resulting profits? Be sure to prove your answer.

Javier, a 85 kg volleyball player, lands on his feet after blocking a shot and immediately jumps back up. When his feet first contact the ground his velocity is 4 m/s downward. When he leaves the ground 0.9 s later he leaves with a velocity of 3 m/s upward. What was is the net impulse that acts on Javier while he is on the ground in Ns?
