 Homework Statement:

Ball A travelling with velocity, , collides headon with stationary ball B in an elastic collision. If the mass of ball A is much greater than the mass of ball B, what is the velocity of ball B immediately after impact?
0 (It remains stationary.)
v (the initial velocity of ball A)
2 v (twice the initial velocity of ball A)
0.5 v (half the initial velocity of ball A)
 Relevant Equations:
 N/A
I'm a little confused as to what the answer could be. This was one of my homework questions that I got wrong as I chose 0.5 v as the answer. Would someone be able to tell me what the correct answer would be?
