A solid, horizontal cylinder of mass 11.0 kg and radius 1.00 m rotates with an angular speed of 5.50 rad/s about a fixed vertical axis through its center. A 0.250-kg piece of putty is dropped vertically onto the cylinder at a point 0.900 m from the center of rotation and sticks to the cylinder. Determine the final angular speed of the system.

A solid cylinder is mounted above the ground with its axis of rotation oriented horizontally. A rope is wound around the cylinder and its free end is attached to a block of mass 76.0 kg that rests on a platform. The cylinder has a mass of 275 kg and a radius of 0.480 m. Assume that the cylinder can rotate about its axis without any friction and the rope is of negligible mass. The platform is suddenly removed from under...
9. You are riding your bike and the brakes fail and the only way to stop before you end up over scenic drive is to use your leg and apply a torque to the tire to stop it in 2.0s. What torque is necessary to stop the bike if the tires radius is 0.33 with a mass of 1.5 kg and rotating at 98.7 rad/s? 10. They made some improvements to the new hover disk that exploded on you once...
