((8.27)Q:7)

Two ice skaters, Daniel (mass 70.0 kg ) and Rebecca (mass 45.0kg ), are practicing. Daniel stops to tie his shoelace and, whileat rest, is struck by Rebecca, who is moving at 14.0 m/s before shecollides with him. After the collision, Rebecca has a velocity ofmagnitude 8.00 m/s at an angle of 55.1 ∘ from her initialdirection. Both skaters move on the frictionless, horizontalsurface of the rink.

A) What is the magnitude of Daniel's velocity after thecollision?

B) What is the direction of Daniel's velocity after thecollision?

C) What is the change in total kinetic energy of the two skatersas a result of the collision?
