Two ice skaters, Daniel (mass 70.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest,

Two ice skaters, Daniel (mass 70.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 14.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 7.00 m/s at an angle of 53.1 from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Collision in a horizontal plane. Part A What is the magnitude of Daniel's velocity after the collision?
