As you are riding in a 1650-kg car, you approach a N7M.8 hairpin curve in the road whose radius is 50 m. The road- bed is banked inward at an angle of 10° (a) Suppose the road is very icy, so that the coefficient of static friction is essentially zero. What is the maximum speed at which you can go around the curve? (b) Now suppose the road is dry and that the static friction coefficient between the tires and the asphalt road is 0.6. What is the maximum speed at which you can safely go around the curve?

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 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
