1. The problem statement, all variables and given/known data There are 2 pucks with different masses. Puck 2 is initially at rest, and Puck 1 is moving horizontally in the positive x direction. The collision has sent the pucks off at angles θ1 and θ2 measured relative to the x-axis, along which Puck 1 initially traveled. Assume momentum is conserved for this collision and write the conservation of momentum expression for each of the two dimensions. 2. Relevant equations 3. The attempt at a solution I list out my variables. mass m1, m2 velocities vix1 viy1=0 vfx1=vf1*cos(θ1) vfy1=vf1*sin(θ1) vix2=0 viy2=0 vfx2=vf2*cos(θ2) vfy2=vf2*sin(θ2) Here i set up the problem. Pfsysx=Pisysx m1(vf1*cos(θ1)) +m2(vf2*cos(θ2)) = m1(vix1) Pfsysy=Pisysy m1(vf1*sin(θ1)) +m2(vf2*sin(θ2)) = 0 does this seem right? can i go any further?
