Question

A 0.02 kg ball moving to the right at 0.25 m/s makes an elastic head-on collision with a 0.04 kg ball moving to the left at 0.15 m/s. After the collision, the smaller ball moves to the left at 0.16 m/s. What is the velocity of the 0.04 kg ball after collision?

Answer 1

M1*V1 + M2*V2 = M1*V3 + M2*V4
0.02*0.25 - 0.04*0.15 = 0.02*(-0.16) + 0.04*V4
0.005-0.006 = - 0.0032 + 0.04*V4
-0.001 + 0.0032 = 0.04*V4
0.04*V4 = 0.0022
V4 = 0.055 m/s.
