Two hockey pucks of equal mass, one red and one blue, are involvedin an elastic collision. The red puck is initially at rest and isstruck by the blue puck moving with speed of 1.5 m/s in the xdirection. After the collision, the blue puck moves along adirection that makes an angle 20 deg bellow the x axis. Determine the final speed of each puck; write the answer in vector direction.
