After the spring is released M has
velocity v. The total energy initially
stored in the spring was:
1.mv
2.2mv
3.3mv
4.4mv
5.5mv
6.None of the above
7.Cannot be determined"
[Ques. 6] A cart of mass m is moving with speed v. Is it possible for the cart's kinetic energy or the magnitude of its momentum to be larger after it collides with something?
1.No; it is impossible.
2.Yes; the kinetic energy can be larger.
3.Yes; the momentum can be larger.
4.Yes; both can be larger.
[Ques. 7] Compare two collisions that are perfectly inelastic. In case (A) a car traveling with speed V collides head-on with a sports car having half the mass and traveling in the opposite direction with twice the speed. In case (B) an identical car traveling with the same speed V collides head-on with a light truck having twice the mass and traveling in the opposite direction with half the speed.
