Two ice skaters, Daniel (mass 70.0 ) and Rebecca (mass 45.0 ), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 14.0 before she collides with him. After the collision, Rebecca has a velocity of magnitude 8.00 at an angle of 52.1 from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink.
