Question 1: Choice Multiple (7 Points) Q(1-5)A driver noticed that there is a hazard on the road. She slams on brakes to stop the car. She had two options while she is going to stop: either to hit a haystack or to hit a cement wall. She was driving initially with 60.0 miles/h, and finally she will stop the car. Answer all the questions regarding this scenario: 1. The change is the car's momentum is greater: a. When she hits the cement wall a. When she hits the haystack. b. It is the same change in momentum in both cases. 2. The change is the car's velocity is greater: a. When she hits the cement wall b. When she hits the haystack. c. It is the same change in velocity in both cases. 3. The Impulse that acts on the car is greater: a. When she hits the cement wall b. When she hits the haystack. c. It is the impulse in both cases.

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object
