A car with a mass of 2000kg sits at the top of an incline. The incline is 20.0 m long and makes a 30.0 degree slope with the horizontal. If an average friction force of 4200N impedes the motion, what is the speed of the car at the bottom of the hill? Use energy relationships to solve.

A 1100-kg car sits at rest at the bottom of a 15 degree hill. The driver initiates the accelerator and the engine pushes it up a 15 degree hill with a net force of 4500 N parallel to the hill. There is an effective 0.1 coefficient of kinetic friction. Use energy concepts to calculate the speed of the car after it has moved 40 m along the hill’s surface.

Part A- a box (mass 12.1 kg) sits on a rough incline that makes an angle α = 30.2o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.335 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for...

A block of mass m is initially held at rest at point P on an incline that makes an angle q with respect to horizontal. The coefficient of kinetic friction between the block and the incline is mk. After the block slides down the incline from point P, it starts to slide without friction up a vertical circular track of radius R. When it reaches the top of the circle, the normal force (downward) by the track to the block...
