## Homework Statement

2 particles travel towards each other at 10ms

^{-1}. Particle 1 has a mass of 10kg and particle 2 has a mass of 30kg. It is an inelastic collision.

Find the magnitude of the Impulse of particle 1 and 2.

## Homework Equations

I=Ft=mv-mu

m

_{1}u

_{1}+m

_{2}u

_{2}=(m

_{1}+m

_{2})V

## The Attempt at a Solution

I'm able to calculate the final velocity of the two particles after the collision when they have joined.

((10×10)+(30×10))/(10+30)=10ms

^{-1}

but I cannot now calculate the impulse of any of the particles.

For example for particle 1:

mv-mu=(10×10)-(10×10)=0

Could anyone help?
