Daniel with mass 65.0 kg and Rebecca with mass 45.0 kg areskating. While Daniel stands at rest, He is struck by Rebecca. Sheis moving at 13.0 m/s before she collides with him. Rebecca has avelocity of magnitude 6.00 m/s at an angle of 55.1 ∘ from herinitial direction after the collision. Both skaters move on thefrictionless and horizontal surface .
a)Find the magnitude of Daniel's velocity after thecollision?
b)Find the direction of Daniel's velocity after the collision? ∘from the Rebecca's original direction
c)Find the change in total kinetic energy of the two skaters as aresult of the collision?
