Question

A ball with a mass of 2 kg traveling at 8 m/s strikes a ball of mass 4 kg traveling 2m/s. After collision, both balls move at the same velocity (v). What is the magnitude of velocity?​

Answer 1

Answer:

4

Explanation:

by applying momentum conservation

2×8+4×2=2×v+4×v

16+8=6v

v=4m/s
