A 5-kg ball rolling at a speed of 3 m/s strikes
a 2-kg ball at rest. The 5-kg ball then comes to
a stop and the 2-kg ball begins to roll forward.
Determine how fast the 2-kg ball is moving

Respuesta :

The velocity of 2-kg ball is will be 7.5 m/sec. Apply law of conservation of momentum principle in given problem.

What is the law of conservation of linear momentum?

According to the law of conservation of linear momentum before the collision is equal to the momentum after the collision. These laws state that about how momentum gets conserved.

Apply law of conservation of momentum principle;

m₁v₁+m₂v₂=(m₁+m₂)V

5 kg×3 m/s+2 kg×0=2kg*V

15 kg m/s=2 kg × V

V=7.5m/s

Hence, the velocity of 2-kg ball is will be 7.5 m/sec
