(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

p=mv

ΔP_{1}+ ΔP_{2}= (F_{1}+ F_{2})(Δt)

3. 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.
