Using the work and energy relations, solve for the constant force "P" required for a system consisting of three blocks given in the figure to have a velocity of 5 m/s when it is moved 2 m after it is released. The coefficient of friction between the blocks and the surface is 0.3 and it will be assumed that the rollers are frictionless. Weights of the rollers W A =400 N; W B = 1000 N and WC = 200 N B.

Block A (mass 40 kg) and block B (mass 80 kg) are connected by a string of negligible mass as shown in the figure. The pulley is frictionless and has a negligible mass. If the coefficient of kinetic friction between block A and the incline is Hk = 0.26 and the blocks are released from rest, determine the change in the kinetic energy of block A as it moves from C to D, a distance of 15 m up the incline.

When an automobile moves with constant speed down a highway, most of the power developed by the engine is used to compensate for the mechanical energy loss due to frictional forces exerted the car by the air and the road. If the power developed by the engine is 205 hp, estimate the total friction force acting on the car when it is moving at a speed of 25 m/s. One horsepower equals 746 W. Need Help?
