A crate of mass 10.5 kg is pulled up arough incline with an initial speed of 1.50 m/s. The pulling forceis 100 N parallel to the incline, which makes an angle of17.5° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.75 m.
(a) How much work is done by gravity?
(e) What is the speed of the crate after being pulled 4.75 m?
