A crate of mass 14.0 kg is pulled upa rough incline with an initial speed of 1.50 m/s. The pullingforce is 100 N parallel to the incline, which makes an angle of18.0° with the horizontal. Thecoefficient of kinetic friction is 0.400, and the crate is pulled4.55 m.

(a) How much work is done by gravity?

(b) How much mechanical energy is lost due to friction?

(d) What is the change in kinetic energy of the crate?

(e) What is the speed of the crate after being pulled 4.55 m?
