A crate of mass m slides down a ramp. The ramp has a length of l and inclined at an angle ?. 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?
