An elastic collision occurs between two air hockey pucks in which one puck is at rest and the other is moving with a speed of 0.7 m/s. After the collision, the puck initially in motion makes an angle of 20.00^o with its original direction, and the struck puck moves at an angle of 70.00^o on the other side of the original direction. What is the final speed of the first puck? What is the speed of the second?
