A 10 kg crate is pulled up a rough incline with an initial speed of 1.5 m/s. The pulling force is 86 N parallel to the incline, which makes an angle of 30 ° with the horizontal. Assuming the coefficient of kinetic friction is 0.4 and the crate is pulled a distance of 7.5 mfind 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 crage
e) the speed of the crate after it is pulled the 7.5 m
