A 50 kg crate slides down a 6 m ramp inclined at an angle of 35 degrees to the horizontal. A worker pushes on the crate parallel to the ramp so that it slides down with a constant velocity. If the coefficient of kinetic friction is .33
a) write equations of motion for the system
c) compute the force of kinetic friction and find the work done by kinetic friction
d) how much work is done by gravity?
A detailed step-by-step solution provided for all the four questions.
