Two identical pucks are set on a collision course on an air table. Puck A's initial direction is 36 degrees above the +x-axis. Puck B's initial direction is 36 degrees above the -x-axis. After the collision, Puck A has a final velocity of 5.00 cm/s at an angle of 28 degrees from the vertical(+y) and Puck B has a final velocity of 4.00 cm/s at an angle of 32 degrees from the vertical (+y). Determine the initial speeds of both pucks. So far I tried breaking the equation mv_Ai+mv_Bi = mv_Af+mv_Bf into components and such. 2 unknown initial speed, system of equations?
