You are given two carts, a and b. they look identical, and you are told that they are made of the same material. you place a at rest on an air track and give b a constant velocity directed to the right so that it collides elastically with a. after the collision, both carts move to the right, the velocity of b being smaller than what it was before the collision.
what do you conclude?
a. cart a is hollow.
b. the two carts are identical.
c. cart b is hollow.
