A cart traveling at 0.3 m/s collides with stationary object. After the collision, the cart rebounds in the opposite direction. The same cart again traveling at 0.3 m/s collides with a different stationary object. This time the cart is at rest after the collision. In which collision is the impulse on the cart greater?
A. The first collision.
B. Cannot be determined without knowing the rebound speed of the first collision.
C. The second collision.
D. Cannot be determined without knowing the mass of the cart.
E. The impulses are the same.
