A load of straw bales is parly on the hood of Jaguar sedan and party on the back of a pickup truck. Both vehicles are facing in the same direction. The pickup is is front of the Jaguar. The truck driver claims that he was stopped at the stop sign when the Jag drove into the back of his truck. The Jaguar driver claims that he was stopped behind the pickup when the truck suddenly backed up.
Choices: True, False
A.) These results are impossible. The bales would have fallen forward in this type of accident.
B.) There isn't enough information to determine who is at fault.
C.) The pickup must have backed into the Jaguar.
D.) The pickup could have backed into the Jaguar.
E.) If the vehicles were both moving (truck in reverse, Jaguar forward), the pickup must have been moving faster.
F.) Regardless of fault, the apparent motion of the bales results from them seeking the natural state of rest.

A puck is resting on the floor of a large moving van. Assume that the floor of the van is frictionless. The van and the puck are initially at rest, then the van undergoes a positive uniform acceleration.
A.) The puck will move forward with respect to the ground. (True or False)
B.) The acceleration of the puck with respect to the ground is (greater than, equal to, or less than) the acceleration of the van with respect to the ground.
C.) The magnitude of the acceleration of the puck with respect to the van is (equal to, less than, or greater than) the magnitude of the van's acceleration with respect to the ground.
D.) The puck will move toward the back of the van. (True or False)
E.) If the van turns to the right, the puck will hit the left wall. (True or False)
F.) The puck is stationary with respect to the van during this acceleration. (True or False)
