## Homework Statement

Two hockey pucks collide in a 90 degree angle and stick to each other. What's the speed of the hockey pucks after the collision and in what angle are the pucks moving in.

## Homework Equations

m1=0.71kg

m2=0.52kg

v1=1.6m/s

v2=3.8m/s

## The Attempt at a Solution

m1v1+m2v2=v(m1+m2)

=0.71kg*1.6m/s+0.52kg*3.8m/s=(0.71kg+0.52kg)*v

=v=(3.1kgm/s)/1.23kg=2.52m/s
