A playground merry-go-round of radius 2.00 m has a moment of inertia I = 230 kgm2 and is rotating about a frictionless vertical axle. As a child of mass 25.0 kg stands at a distance of 1.00 m from the axle, the system (merry-go-round and child) rotates at the rate of 14.5 rev/min. The child then proceeds to walk toward the edge of the merry-go-round. What is the angular speed of the system when the child reaches the edge?

The force exerted on a spring is proportional to the distance in which the spring stretches from its relaxed positon. Suppose u stretch a spring distance d in inches by applying force F in pounds. For a spring d/f=0.8. you apply forces between 25 and 40 pounds, inclusive. Write a compound inequality describing the stretch of the spring.
