A boy pulls a 26.0-kg box with a 100-N force at 36° above a horizontal surface. If the coefficient of kinetic friction between the box and the horizontal surface is 0.15 and the box is pulled a distance of 40.0 m, what is the net work doneon the box?

A 3.7-kg block is pushed 2.3 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of 0 = 30° with the horizontal, as shown in the figure below. If the coefficient of kinetic friction between block and wall is 0.30, determine the following. (a) the work done by F (b) the work done by the force of gravity (c) the work done by the normal force between block and wall (d) By how much does the gravitational potential energy increase during the block's motion?

A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. Enter an expression for the minimum angle θ (in degrees) the box will begin to slide.  Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is large enough that it will move down the plank.  For a plank of any length, at what angle θ (in degrees) will the final speed of the box at the bottom of the plank be 0.55 times the final speed of the box when there is no friction present? Assume μk = 0.35.

Solve for the weight component (N), work done by applied force (J), and work done by weight component (J). Please show solution. Shown below is the sample figure with different angle.  Given: mass = 3.0 kg displacement = 1.19 m applied force = 25.5 N angle = 60 degrees

A water-skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 73.5-kg water-skier has an initial speed of 5.2 m/s. Later, the speed increases to 12.2 m/s. Determine the work done by the net external force acting on the skier. W =

F A 2.3 kg block is moved at constant speed over a surface for which the coefficient of kinetic friction is 0.26. The displacement is 6 m. It is pushed by a force directed at 34 degrees below the horizontal as shown in the figure above. Find the work done on the block by: a) the force; a) friction; a) gravity.
