A pulley with a mass M and a radius R is mounted on a frictionless horizontal axle passing throughthe center of the pulley. A block with a mass M hangs down from a string that is wrapped around theoutside of the pulley. Assume that the pulley is a uniform solid disk.1. Determine the acceleration of the block when the system is released from rest. ( the masses ofthe pulley and the hanging block are the same)2. What is the speed of the block after it falls for 1.5 m?3. How many revolutions did the pulley make at that time?

4. A pinball of mass M and radius R is pushed against a spring of spring constant k. The spring is compressed a distance D and the pinball machine ramp is inclined at an angle 0. The spring is then released. The pinball is a solid metal sphere that rolls without slipping. a. Determine the speed of the pinball as it leaves the spring. Hint: the spring force is not constant so you cannot use constant acceleration kinematics. Use conservation of mechanical energy instead. b. What is the distance that the pinball would go up the ramp before coming back down?
