4. A small ball of mass m, suspended by a cord of length L, revolves in a circle of radius r= Lsine, where 0 is the angle the string makes with the vertical. (a) Determine the horizontal and vertical components of the force exerted by the cord, in what direction is the acceleration of the ball, and what causes the acceleration? (b) Calculate the speed and neriod (time required for one revolution ) of the ball in terms of L, 0,and m.

A cat dozes on a stationary merry-go-round, at a radius of 5.40 m from the center of the ride. Then the operator turns on the ride and brings it up to its proper tuning rate of one complete revolution every 6.00 s. What is the least coefficient of static friction between the cat and the merry-go-round that will allow the cat to stay in place when it is to the right of the center of the ride, without sliding? The three forces acting on the cat must be identified. Which forces act on the cat? Gravitational force Static frictional force Tension Kinetic frictional force Normal force

What is the least coefficient of static friction between the cat and the merry-go-round that will allow the cat to stay in place when it is to the right of the center of the ride, without sliding? The directions of the three forces and the acceleration must be identified. Make a free-body diagram. Please use the blue vector to specify forces and the pink vector for acceleration. Assume that the center of rotation is to the left. DO NOT forget to label each vectors with none, mg, T, a, or FN
