Two ice skaters, Daniel (mass 70.0kg ) and Rebecca (mass 45.0kg ), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 14.0m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 6.00m/s at an angle of 53.1∘ from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink.
What is the magnitude of Daniel's velocity after the collision?
