The answer would be

A 50-g ball moving at 10 m/s in the + x direction suddenly collides head-on with a stationary ball of mass 100 g. If the collision is perfectly elastic, what is the velocity of each ball immediately after the collision?

A) - 3.3 m/s, + 6.7 m/s

B) + 3.3 m/s, - 6.7 m/s

C) - 6.7 m/s, + 3.3 m/s

D) + 6.7 m/s, - 3.3 m/s

The answer would be A.
