Mahmut with mass 70.0 kg and Güllü with mass 45.0 kg are skating. While Mahmut stands at rest, He is struck by Güllü. She is moving at 15.0 m/s before she collides with him. Güllü has a velocity of magnitude 10.00 m/s at an angle of 55.0 ∘ from her initial direction after the collision. Both skaters move on the frictionless and horizontal surface .

a)Find the magnitude of Mahmut's velocity after the collision?

b)Find the direction of Mahmut's velocity after the collision?

c)Find the change in total kinetic energy of the two skaters as a result of the collision?

Two ice skaters, Daniel (mass = 65.0 kg) and Rebecca (mass = 45.0 kg) are practicing on the ice. Daniel stops to tie his lace, and while at rest he is struck by Rebecca, who is moving 12.0 m/s before she collides with him. After the collision, Rebecca is moving forward at 8.50 m/s at a 53 degree angle with respect to her initial direction. What is the velocity vector (magnitude and direction, or x- and y-components) of Daniel after...

Two friends, Al and Jo, have a combined mass of 166 kg. At the ice skating rink, they stand close together on skates, at rest and facing each other. Using their arms, they push on each other for 1 second and move off in opposite directions. Al moves off with a speed of 5.9 m/sec in one direction and Jo moves off with a speed of 9.7 m/sec in the other. You can assume friction is negligible. 1)What is Al's...
