## Homework Statement

A .5kg hockey puck moving at 2 m/sec strikes another puck with a mass of 1kg. The puck then travels at an angle of 60 degrees with a speed of .75m/sec with respect to the motion of the original puck.

a) What is the final speed of the first puck?

b) What is the final direction of the first puck?

m

_{1}=.5kg

m

_{2}=1kg

v

_{1}=?

v

_{2}=.75 m/sec

## Homework Equations

p=mv

ΔP

_{1}+ ΔP

_{2}= (F

_{1}+ F

_{2})(Δt)

## The Attempt at a Solution

m

_{1}u

_{1}= (m

_{1}+m

_{2})v cos60

m

_{2}u

_{2}= (m

_{1}+m

_{2})v sin60

This is all I can get. I think I'm right so far lol. I need help badly! This momentum stuff is killing me.
