A hockey puck moving along the +x axis at 0.42 meter per second collides into another puck that is at rest. The pucks have identical mass. The first puck is deflected 37o below the +x axis and moves off at 0.36 m/s.
Obtain the speed and direction of the second puck after the collision.
Compute what is the speed?
Compute what is the direction?
