Two ice skaters, Daniel (mass 65.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, whois moving at 13.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 8.00m/s at an angle of from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink.
A. What is the magnitude of Daniel's velocity after the collision?
B. What is the direction of Daniel's velocity after the collision?
