# Collision

An object of mass 2 kg travelling in a straight line with a velocity of 20m/sec collides with, and strikes to, a stationary object of mass 3 kg. They both move off together in the same straight line with a velocity of v m/sec. If no external forces are acting calculate

a. the total momentum just before the impact

b. the total momentum just after the impact

c. the velocity v.

#### Solution Preview

Momentum of the system = m1 * v1 + m2 * v2.

<br>

<br>The total momentum just before the impact:

<br>Momentum of the 2 kg mass is 2 kg * 20 ...

#### Solution Summary

This solution calculates the momentum and velocity of two colliding objects.
