Note that the total mechanical energy of a system remains constant in any isolated
system of objects that interact only through conservative forces.

A 3.00-kg crate slides down a ramp. The ramp is 1.00 m in length
and inclined at an angle of 30.0°, as shown in Figure 8.8. The
crate starts from rest at the top, experiences a constant frictional
force of magnitude 5.00 N, and continues to move a short
distance on the flat floor after it leaves the ramp. Use energy
methods to determine the speed of the crate at the bottom of the
ramp.
