Question

A hockey puck (1) of mass 170 g is shot east at a speed of 9.00 m/s. It strikes a second puck (2), initially at rest, of mass 187 g. As a result of the collision, the first puck (1) is deflected at an angle of 66° south of east and the second puck (2) moves at an angle of 40° north of east. What is the magnitude of the velocity of puck (2) after the collision?
