A crate of mass 10.5 kilogram is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100 Newton parallel to the incline, which makes an angle of 20.0 degree with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.20 meter.

(a) Find how much work is done by gravity?

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

(d) Determine the change in kinetic energy of the crate?

(e) Determine the speed of the crate after being pulled 5.20 meter?
