Question

A 5kg ball moving at 10 m/s to the right collides with a 2 kg ball at rest. After the collision, the 5 kg ball moves at

3.5 m/s to the right. What is the velocity of the of the 2 kg ball? (Elastic collision)

Answer 1

14.29m/s

Step-by-step explanation:

v1' = ((m1 - m2) / (m1 + m2)) v1

v2' = (2m1 / (m1 + m2)) v1

Where

m1,m2 - Mass of Moving Objects

v1 - Velocity of Moving Objects
