Question

A 40.0 kg crate slides down a ramp with a constant velocity of 0.70 m/s. The ramp is inclined at an angle of 14.0 degrees below the horizontal. The friction force acting between the crate and the ramp is 92.0 N.

A) find the air resistance acting on the crate.

B) find the coefficient of kinetic friction between the crate and the ramp.

C) find the net work done by all the forces acting on the crate during the slide:

i) by adding together the work done by each force.

ii) by using the Work - Energy Theorem.
