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...

A small girl is skating around on an ice rink. Her mass is 30 kg, and her speed is 4.0 m/s. She sees a 50 kg sled at rest on the rink that was left there by a careless worker, and she decides to jump onto the sled. Assume no friction between the sled and the ice. a. Find the child-sled system’s speed immediately after the child jumps onto the sled. b. Find the child-sled system’s kinetic energy immediately 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...

A person with mass mp = 70 kg stands on a spinning platform disk with a radius of R = 2.1 m and mass md= 187 kg. The disk is initially spinning at ω = 1.4 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.7 m from the center). 1. What is the total moment of inertia of the system about the center of the disk when the person stands on the...

A child of mass mc = 35 kg stands on the rim of a frictionless merry go round, which acts like a solid disk of mass mm = 55 kg and radius r = 1.1 m. With the merry go round at rest, they throw a rock of mass mr = 1.0 kg with a velocity v = 18 m/s relative to the ground in a direction horizontal to the ground, and tangent to the rim of the merry go...

A person with mass m1 = 68 kg stands at the left end of a uniform beam with mass m2 = 109 kg and a length L = 2.5 m. Another person with mass m3 = 50 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 8 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate...
