A 6.0 kg block is pushed 8.0 m up a rough 37 degree inclined plane by a horizontal force of 75N. If the initial speed of the block is 2.2m/s up the plane and a constant kinetic friction force of 25N opposes the motion, calculate the initial kinetic energy of the block, the work done by the 75N force, the work done by the friction force, the work done by gravity, the work done by the normal force, and the final kinetic energy of the block.© BrainMass Inc. brainmass.com March 4, 2021, 6:04 pm ad1c9bdddf
We set up a graph for all forces on the block. By hypothesis, we ...
