A) the lighter block will have more kinetic energy than the heavier block.
B) the heavier block will have more kinetic energy than the lighter block.
C) both blocks will both have the same amount of kinetic energy.
D) both blocks will have equal speeds.
E) the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block.
Calculations:
A 2.0-kg cart collides with a 1.0-kg cart that is initially at rest on a low-friction track. After the collision, the l.0-kg cart moves to the right at 0.5 m/s and the 2.0-kg cart moves to the right at 0.3 m/s. What was the initial velocity of the 2.0-kg cart?
