1. The problem statement, all variables and given/known data To push a 33 kg crate up a frictionless incline, angled at 15° to the horizontal, a worker exerts a force of 100.4 N, parallel to the incline. As the crate slides 1.50 m, (a)how much work is done on the crate by the worker's applied force? (b) How much work is done on the crate by the weight of the crate? (c) How much work is done on the crate by the normal force exerted by the incline on the crate? (d) What is the total work done on the crate? 2. Relevant equations I can NOT solve (d)!!!! 3. The attempt at a solution I have solved a, b, and c: (a) 1.51 x 10^2 J (b) -1.26 x 10^2 J (c) 0.00 J (d) ?
