A small 0.120 kg sphere is suspended by a light string from a vertical post mounted at the edge of a merry-go-round of radius R = 0.440 m. The equilibrium position of the sphere is shown in the figure, with a = 0.410 m and b = 0.700 m. The axis of rotation is indicated by the dashed line. Calculate the angular velocity of the merry-go-round.
If the steel disk has a mass of 200 kg, a radius of 2 meters, and a smooth low-friction bearing at its center you can make it spin by applying a force to the rim. This torque increases the angular momentum of the disk. Suppose the force is 100 newtons. a. What mass could you pick up with a force of 100 newtons? That will give you a sense of how much force this really is. b. How long would you have to apply this force it to get the wheel spinning 2 times a minute? c. What would happen to the rate of spin if you then jumped on the rim of the wheel with your mass of 75 kg?
