Question

In a collision, a 9 kg ball moving at 5 m/s transfers all of its momentum to a 3 kg ball. What is the velocity of the 3 kg ball after the collision if all momentum is conserved?

Answer 1

Answer:

momentum of 1st ball = 9×5 = 45

Transfers the momentum

so Momentum of ball will be 45

so velocity = 45/3 = 15 m/s
