For part d, it's Answer to c-(Answer to b+Answer to a)=The change in kinetic energy of the crate

a) Find the work done by Earth’s gravity on the crate. Weight*Distance sine theta=Work done by the gravity b) Find the work done by the force of friction on the crate. Weight*Distance cos theta*coefficient=Work done by the force of gravity c) Find the work done by the puller on the...

a) Find the work done by Earth’s gravity on the crate. Answer in units of J. I think you have to find the work done on the block parallel to the plane, then find the y component of the work

The displacement is parallel to the plane. If that's what you are asking

Homework Statement A 11.0 kg crate is pulled up a rough incline with an initial speed of 1.3 m/s. The pulling force is 121.0 N parallel to the incline, which makes an angle of 12.6◦ with the horizontal. The coefficient of kinetic friction is 0.31 and the crate is pulled a distance of 8.0 m...
