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? m1=.5kg m2=1kg v1=? v2=.75 m/sec 2. Relevant equations p=mv ΔP1 + ΔP2 = (F1 + F2)(Δt) 3. 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.
