A crate of mass 10.0 kg is pulled up a rough incline with aninitial speed of 1.50 m/s. The pulling force is 100 N parallel tothe incline, which makes an angle of 17.5° with the horizontal. Thecoefficient of kinetic friction is 0.400, and the crate is pulled5.55 m.
(a) How much work is done by gravity?
(b) How much mechanical energy is lost due to friction?
(c) How much work is done by the 100 N force?
(d) What is the change in kinetic energy of the crate?
(e) What is the speed of the crate after being pulled 5.55 m?
