A 3.50-kg crate starting at rest slides down a rough 6.80-m-long ramp, inclined at 25.0° below the horizontal. The magnitude of the force of friction between the crate and the ramp is 8.30 N.

(a) How much work is done on the crate by friction?
 J

(b) What is the change in potential energy of the crate in sliding down the ramp?
 J

(c) What is the speed of the crate at the bottom of the incline?
 m/s

A crate of fruit with mass 35.0 kg and specific heat capacity 3650 J/kg K slides down a ramp inclined at 36.8 degrees below the horizontal. The ramp is 8.00 m long. a) If the crate was at rest at the top of the incline and has a speed of 2.50 m/s at the bottom, how much work was done on the crate by friction?

A 15kg crate, initially at rest slides down a ramp 2.0m long and inclined at an angle of 20 degrees with the horizontal. If there is a constant force of kinetic friction of 25 N between the crate and ramp, what kinetic energy would the crate have at the bottom of the ramp?

A crate of mass m slides down a ramp. The ramp has a length of 'l' and inclined at an angle θ. The crate starts from rest at the top, experiences a constant friction force of magnitude F, and continues to move a short distance on a horizontal floor after it leaves the ramp.
Determine the speed of the crate at the bottom of the ramp. How far does the crate slide on the horizontal floor if it continues to experience a friction force of magnitude F?
