Question

a collision between two pucks on an air-hockey table. Puck A has a mass of 0.025 kg and is moving along the x axis with a velocity of +5.5 m/s. It makes a collision with puck B, which has a mass of 0.060 kg and is initially at rest. The collision is not head-on. After the collision, pluck A goes in 65degree above + Xaxis, Pluck B is 37 degree below +X axis. what's final speed of pluck A and pluck B?
