A motorcycle has a constant speed of 24.5 m/s as it passes over the top of a hill whose radius of curvature is 174 m. The mass of the motorcycle and driver is 309 kg. Find the magnitude of (a) the centripetal force and (b) the normal force that acts on the cycle

A racetrack curve has radius 90.0 m and is banked at an angle of 18.0. The coefficient of static friction between the tires and the roadway is 0.400. A race car with mass 1200 kg rounds the curve with the maximum speed to avoid skidding. (a) As the car rounds the curve, what is the normal force exerted on it by the road? What are the car’s (b) radial acceleration and (c) speed?

A curve in a road forms part of a horizontal circle. As a car goes around it at constant speed 14.0 m/s, the total horizontal force on the driver has magnitude 130 N. What is the total horizontal force on the driver if the speed on the same curve is 18.0 m/s instead?

A bucket of mass 2.00 kg is whirled in a vertical circle of radius 1.10 m. At the lowest point of its motion the tension in the rope supporting the bucket is 25.0 N.(a) Find the speed of the bucket.(b) How fast must the bucket move at the top of the circle so that the rope does not go slack?

A small block with mass 0.0300 kg slides in a vertical circle of radius 0.550 m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 3.75 N. In this same revolution, when the block reaches the top of its path, point B, the magnitude of the normal force exerted on the block has magnitude 0.685 N.

A car is driving along a circular track with diameter d = 0.59km at a constant speed of v = 21.2 m/s.  Write an expression and find the value for the minimum coefficient of friction between the cars tires and road required in order to keep the car going in a circle in terms of the given parameters.

A 30 kg object is moving in uniform circular motion with a radius of 10 m. It takes the object 2 s to make one complete revolution. Find the net force acting on the object.

A 49.0-kg child takes a ride on a Ferris wheel that rotates four times each minute and has a diameter of 19.0 m. (a) What is the centripetal acceleration of the child?(b) What force (magnitude and direction) does the seat exert on the child at the lowest point of the ride?(c) What force does the seat exert on the child at the highest point of the ride?(d) What force does the seat exert on the child when the child is halfway between the top and bottom?

"plastered" against the wall. Suppose the radius of the room is 3.91 m and the speed of the wall is 13.9 m/s when the floor falls away. The source of the centripetal force on the riders is the normal force provided by the wall. (a) How much centripetal force acts on a 54.5 kg rider? (b) What is the minimum coefficient of static friction that must exist between the rider's back and the wall, if the rider is to remain in place when the floor drops away

A small block with mass 0.0300 kg slides in a vertical circle of radius 0.425 m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 3.90 N . In this same revolution, when the block reaches the top of its path, point B, the magnitude of the normal force exerted on the block has magnitude 0.675 N .   1) How much work was done on the block by friction during the motion of the block from point A to point B?
