a 50 kilogram box is pushed up a 10.0 meter long ramp. the high end of the ramp is elevated 6.0 meters above the low end. (the ramp forms a 3-4-5 triangle). while moving the 10 meters up the ramp the box accelerates from 0.0 meters per second to 2.0 meters per second.

A.) how much work against inertia was performed;

B.) how much work against gravity was performed; and

C.) if the coefficient of kinetic friction was 0.25, how much work against friction was performed?
