A crate of mass 10.6 kg is pulled up a rough incline with an initial speed of 1.52 m/s. The pulling force is 90 N parallel to the incline, which makes an angle of 19.6 with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.08 m
(a) How much work is done by the gravitational force on the crate?
(b) Determine the increase in internal energy of the crate%u2013incline system owing to friction.
(c) How much work is done by the 90-N force on the crate?
(d) What is the change in kinetic energy of the crate?
(e) What is the speed of the crate after being pulled 5.08 m?
