Daniel with mass 65.0 kg and Rebecca with mass 45.0 kg are
skating. While Daniel stands at rest, He is struck by Rebecca. She
is moving at 13.0 m/s before she collides with him. Rebecca has a
velocity of magnitude 6.00 m/s at an angle of 55.1 ∘ from her
initial direction after the collision. Both skaters move on the
frictionless and horizontal surface .
a)Find the magnitude of Daniel's velocity after the
collision?
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 a
result of the collision?
