1. The problem statement, all variables and given/known data Two hockey pucks collide with each other. Puck 1 has a mass of 0.050 kg and an initial velocity of 5 m/s in the x direction. It collides with puck 2 which is initially at rest and has a mass of 0.10 kg. The collision isn't head-on. After the collision, Puck 1 flies off in the north-east direction with a velocity of 3 m/s in an angle θA above the x-axis. Puck 2 flies off in the southeast direction with a velocity of 2.5 m/s in an angle θB below the x-axis. Find θA and θB. 2. Relevant equations Conservation of linear momentum m1vf1 + m2vf2 = m1vo1 + m1vo2 3. The attempt at a solution So in the y: m1vf1y + m2vf2y = m1vo1y + m1vo2y 0.05(3sinΘa) + 0.1(2.5sinΘb) = 0 + 0 0.15sinΘa + 0.25sinΘb = 0 In the x: m1vf1x + m2vf2x = m1vo1x + m1vo2x 0.05(3cosΘa) + 0.1(2.5cosΘb) = 0.05(5) + 0 0.15cosΘa + 0.25cosΘb = 0.25 I'm lost as to where to go from here.
