Question

A 60 kg mass is moving at 5 m/s and collides with a 2 kg mass. All the momentum of the first mass is transferred in the collision to the second mass. What will the velocity (in m/s) be for the 2 kg mass?

Answer 1

v = 150 [m/s]

Step-by-step explanation:

Linear momentum is defined as the product of mass by Velocity. In this way, by means of the following equation, we can calculate the momentum.

`P=m*v\\`

where:

m = mass [kg]

v = velocity [m/s]

`P =60*5\\P =300 [kg*m/s]`

Since all momentum is transferred, we can say that this momentum is equal for the mass of 2 [kg]. In this way, we can determine the speed after the impact.

`v = P/m\\v = 300/2\\\\v = 150 [m/s]`
