A 33.00 kg block starts from rest at the top of a 23.0 m long 30.0° incline. Its kinetic energy at the bottom of the incline is 3719.1 J. How much work is done by friction?

A bicyclist starting from rest applies a force of F = 239 N to ride his bicycle across flat ground for a distance of d = 210 m before encountering a hill making an angle of θ = 17 degrees with respect to the horizontal. The bicycle and rider have a mass of m = 120 kg combined. In this problem, you can ignore air resistance and other losses due to friction.How much work, W in joules, did the rider do before reaching the hill? What is the bicycle's speed, v in m/s, just before the hill? If the cyclist starts coasting at the bottom of the hill, what distance, di in meters, does the bike travel up the incline?

The graph shows the x component of a force that acts on an object that moves on the x axis. The vertical spacing between adjacent grid lines is 4.98N, while the horizontal spacing between adjacent grid lines is 1.0m. What is the work, in joules, done by the force as the object moves from x = 4m to x = 5m ? F (N) C C 0 x (m)

A 19.1-kg box is being pushed from the bottom to the top of a frictionless ramp. When the box is pushed at a constant velocity, the nonconservative pushing force does 58.0 J of work. How much work is done by the pushing force when the box starts from rest at the bottom and reaches the top of the same ramp with a speed of 1.50 m/s?

A 15.0-kg object is pulled along a horizontal surface at a constant speed by a 25 N force acting at 30° above the horizontal. How much work is done by this force as the object moves 10.0 m?
