A block of weight mg sits on an inclined plane as shown. A force of magnitude F is applied to pull the block up the incline at constant speed. The coefficient of kinetic friction between the plane and the block is Mu.
What is the total work done on the block by the force of friction as the block moves a distance L up the incline? Express the work done by friction in terms of any or all of the variables Mu, m, g, teta , L and F.

What is the total work Wf done on the block by the applied force F as the block moves a distance L up the incline? Express your answer in terms of any or all of the variables Mu,m,g,teta,L,F

Now the applied force is changed so that instead of pulling the block up the incline, the force pulls the block down the incline at a constant speed

What is the total work Wfriction done on the block by the force of friction as the block moves a distance down the incline?

What is the total work Wf done on the box by the appled force in this case?

A 12 kg block is released from rest on a 30 degree frictionless incline. Below is a block that can be compressed 2.0 cm by a force of 270 N. The block momentarily stops when it compresses the spring by 5.5 cm. How far does the block move down the incline from its rest position to this stopping point? What is the speed of the bl

A block of mass m = 2.00 kg is released from rest at h = 0.400 m from the surface of a table, at the top of a theta = 40.0 degrees incline as shown below. The frictionless incline is fixed on a table of height H = 2.00 m.

A 2.00 kg block is pushed against a spring with negligible mass and force constant k = 400 N/m, compressing it 0.220 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope 37 degrees.

A m1 = 49.0 kg blockand an m2 = 103.0 kg block are connected by a string as in Figure P7.28. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between the 49.0 kg blockandincline is 0.250. Determine the change in the kinetic energy of the 49.0 kg block as it moves from A to B, a distance o

Please show your work as I need to understand the solution well.
A block of mass 2.0 kg resting on a horizontal frictionless surface is initially held against a spring of constant 5200 N/m that is compressed by 13 cm from its normal length. After the block is released, it slides along the frictionless surface until it encount

A triangular piece of wood is free to slide, without friction, in one dimension along a table, forming a moving inclined plane. A block of wood, placed on this inclined plane only moves as the result of the triangular block moving. There is no friction between the triangular piece of wood and the block. Find the lagrangian fo

Two blocks, A and B (with mass 50 kg and 100 kg, respectively), are connected by a string, as shown in Figure. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is µk = 0.29. Determine the change in the kinetic energy of block A as it moves from C to D, a dist

A block of mass m starts from rest at a height h and slides down a frictionless plane inclined at theta with the horizontal. The block strikes a spring of force constant k. Find the compression of the spring when the block is momentarily at rest.
