A man pulls a 101.0 N crate up a frictionless ramp that is inclined at 0.9768 rad above the horizontal, starting at the bottom and going all the way to the top. The ramp is 5.143 m high, and the pulling force is parallel to the surface of the ramp. Assuming that the crate moves at a constant speed, calculate how much work did the man did on the crate. NOTE: Be sure to include units. W

You push a crate of mass m up a ramp inclined at an angle A with...

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...
