a 1300 newton crate slides 14 meters down a ramp that makes an angle of 30 degree with the horizontal. if the crate slides at a constant speed, how much thermal energy is created?
All of the potential energy lost is converted to heat, since the kinetic energy does not change.
The potential energy loss is
(Weight)x(Change in Height)
= 1300 N * 14 m sin 30 = __?_ Joules
