Physics Question =]?
A 10.0 kg crate is pushed up a 15 deg. incline with an initial speed of 1.5 m/s. The force pulling the crate is 100,0 N and is parallel to the surface of the incline. Assuming the coefficient of kinetci friction is 0.40 and the crate is pulled a distance of 7.5 m find the following:
a.) The work done by gravity
I know you don't need all that info for that but you did for parts b,c, and d which are not shown because I solved them already
Haha..sorry I accidentally posted this in the hockey section.

The (negative) work done by gravity is simply distance*m*g*sin(theta). I hope you used m*g*cos(theta) to calculate the normal force from which to calc. the friction force.
