Two identical pucks are on an air table. Puck A has an initial velocity of 2.6 m/s in the positive x-direction. Puck B is at rest. Puck A collides elastically with puck B and A moves off at 2.50 m/s at an angle of +16.3° above the x-axis. What is the speed and direction of puck B after the collision? (Take angles above the x axis to be positive and below to be negative.)

_____ m/s at -73.7 °

2. Relevant equations

??????????

3. The attempt at a solution

I got the angle but I have no idea what the speed would be. Does anybody have like a ball park figure of what it would be? because the answers i get dont even make sense.
