A 44kg goes down throguh an inclined plane of an angle of 26° (over the x-axis) at a constant velocity by applying a horizontal force F, if the coefficient of kinetic friction is 0.17 and the traveled length of the block is 8.5m, what is the work done applied by the friction force?
A 10 kg block is placed on an inclined plane that is at an angle of 30 degrees with respect to the horizontal. THe coefficient of kinetic friction between the block and the plane is .1. The block is released from rest at 5m above a spring that is also lying on the plane. The spring has a constant of 50 N/m. What is the max compression of the spring?
A block of mass 2.0 Kg is sliding down an inclined plane, as shown (the angle is 30 degrees). If the coefficient of kinetic friction is 0.250, determine the net acceleration of the block down the plane.
Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?
A 4.5-kg block slides down an inclined plane that makes an angle of 28° with the horizontal. Starting from rest, the block slides a distance of 2.4 m in 5.2 s. Find the coefficient of kinetic friction between the block and plane.

A block of mass m = 3.5 kg is on an inclined plane with a coefficient of friction μ1 = 0.31, at an initial height h = 0.53 m above the ground. The plane is inclined at an angle θ = 54°. The block is then compressed against a spring a distance Δx = 0.11 m from its equilibrium point (the spring has a spring constant of k1 = 39 N/m) and released. At the bottom of the inclined plane...
A physics student pulls a block of mass m = 22 kg up an incline at a slow constant velocity for a distance of d = 4.5 m. The incline makes an angle ? = 32° with the horizontal. The coefficient of kinetic friction between the block and the inclined plane is µk = 0.3. 1) What is the work Wm done by the student? 2) At the top of the incline, the string by which she was pulling the...
