In a collision, a 25.0 kg mass moving at 3.0 m/s transfers all of its momentum to a 5.0 kg mass.
what is the velocity of the 5.0 kg mass after the collision?

The velocity is 15m/s

The first step is calculate the momentum

= mass × velocity

= 25 × 3

= 75

The velocity of the mass after collision can be calculated as follows

= 75/5

= 15 m/s

Hence the velocity of the 5.0 kg after the collision is 15m/s

Explanation:

The momentum of the 25 kg mass is

If this whole momentum of the object is transferred to the 5.0 kg object then according to the law of conservation of momentum, the momentum of the 25.0 kg object must be transferred to the 5.0 kg object:

the correct choice is a .
