A 10.0 kg crate is pulled up a rough incline with an initialspeed of 1.5 m/s. The pulling force is 100.0 N parallel to theincline, which makes an angle of 15 degrees with the horizontal.Assuming the coefficient of kinetic friction is 0.40 and the crateis pulled a distance of 7.5 m, find the following:

a. the work done by the Earth's gravity on the crate

b. the work done by the force of friction on the crate

c. the work done by the puller on the crate

d. the change in kinetic energy of the crate

e. the speed of the crate after it is pulled 7.5 m.
