A solid disk with a c value of 1/2, mass of 3 kg, and radius of 1.5 meters lies on a horizontally (so the normal force and weight can be ignored). A force of 9 Newtons is applied 0.22 meters directly to the right of the center in the +x direction, a force of 24 Newtons is applied at 0.81 meters directly below of the center in the +x direction and a force of 8 Newtons is applied at the edge of the disk directly above the center in the +x direction. Again, ignoring the weight and normal force, what is the angular velocity of the disk after these forces are applied for 3 sec, in rad/s? If clockwise, include a negative sign.

1) A solid sphere with a radius of 1.3 meters and mass of 3.4 kg is pressed into a step with a height of 0.8 meters, by a force which is applied horizontally 0.5 meters above the center of the sphere (see sketch). When this force is applied, the sphere just starts to live off the ground and pivot around the corner of the step. How much is this force in Newtons?
