Question
Mass A (2.0 kg) has an initial velocity of 4 m/s in the +x-direction. Mass B (2.0 kg) has an initial velocity of 5 m/s in the –x-direction. If the two masses have an elastic collision, what will be the final velocities of the masses after the collision?
a. Both will move 0.5 m/s in the –x-direction.
b. Mass A will stop; mass B will move 9 m/s in the +x-direction.
c. Mass B will stop; mass A will move 9 m/s in the –x-direction.
d. Mass A will move 5 m/s in the –x-direction; mass B will move 4 m/s in the +x-direction.
