A crate of mass 9.8 kg is pulled up a rough incline with an initial speed of 1.56 m/s. The pulling force is 102 N parallel to the incline, which makes an angle of 20.2° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.98 m.

(a) How much work is done by the gravitational force on the crate?

J

(b) Determine the increase in internal energy of the crate-incline system owing to friction.

J

(c) How much work is done by the 102-N force on the crate?

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

J

(e) What is the speed of the crate after being pulled 4.98 m?
