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?
ΔP1 + ΔP2 = (F1 + F2)(Δt)
The Attempt at a Solution
m1u1 = (m1+m2)v cos60
m2u2 = (m1+m2)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.
