Jay with a mass of 60.0 kg skates at 10.0 m/s due north on a frozen horizontal surface towards a crossroad. Kay of mass 51.0 kg who is crossing through the crossroad gets shocked and stops upon spotting Jay. Jay collides with Kay. Jay travels at 6.2 m/s directed at 28.0° east of north after the collision. Determine the magnitude and direction of Kay's velocity following the collision. You may ignore friction.
