Work-Energy Theorem: Three cars (car L, car M, and car N) are moving with the same speed and slam on their brakes. The most massive car is car L, and the least massive is car N. If the tires of all three cars have identical coefficients of kinetic friction with the road surface, for which car is the amount of work done by friction in stopping it the greatest?
A. The amount of work done by friction is the same for all cars.
B. Car L
C. Car M
D. Car N

Basic Postulates: You are riding in a spaceship that has no windows, radios, or other means for you to observe or measure what is outside. You wish to determine if the ship is stopped or moving at constant velocity. How can you do this?
A. You can determine if the ship is moving by determining the apparent velocity of light in the spaceship. B. You can determine if the ship is moving by checking your precision time piece. If it's running slow, the ship is moving. C. You can determine if the ship is moving by lying down and measuring your height. If you are shorter than usual, the ship is moving. D. You should give up because you have taken on an impossible task!
