Consider again the crate in Problem 5, but now include friction. Assume the coefficient of kinetic friction between the crate and the ramp is μ_K= 0.25. What is the work done by the person as he pushes the crate up the ramp?

Data From Problem 5

A crate of mass 24 kg is pushed up a friction less ramp by a person as shown in Figure P6.5. Calculate the work done by the person in pushing the crate a distance of 20 m as measured along the ramp. Assume the crate moves at constant velocity.
