As a result of a glancing collision with the surface of the sphere (see Figure), the velocity of a small ball (mass m = 139 g, shown in green) changes from V0 = 7.0 m/s directed rightward to VF = 5.0 m/s directed 53.1∘ above the horizontal. The ball was in contact with the sphere for a time 0.20 s. [20 pts] What is the magnitude of the change in momentum of the ball?

A disk of mass m1 = 70.0 g and radius r1 = 3.50 cm slides on a frictionless sheet of ice with velocity v→, where v = 14.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m2 = 140 g, a radius r2 = 5.00 cm, and is initially at rest. As the disks make contact, they stick together due to highly adhesive glue on the edge of each, and then rotate after the collision as shown in figure (b). (i) (a) What is the magnitude of the angular momentum (in kg⋅m2 /s ) of the two-disk system relative to its center of mass? kg⋅m2/s (b) What is the angular speed (in rad/s) about the center of mass? rad/s

A torque of 35.0 N⋅m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 9.7 rad/s. After 5.90 s the directed force is removed, and the wheel comes to rest 61.0 s later. (a) What is the wheel's moment of inertia (in kg⋅m2)? kg⋅m2 (b) What is the magnitude of the torque caused by friction (in N⋅m)? N⋅m (c) From the time the directed force is initially applied, how many revolutions does the wheel go through? revolutions
