To push a 27.0 kg crate up a frictionless incline, angled at $27.00$ to the horizontal, a worker exerts a force of 215 N parallel to the incline. As the crate slides 1.70 m, how much work is done on the crate by (a) the workers applied force, (b) the gravitational force on the crate, and (c) the normal force exerted by the incline on the crate? (d) What is the total work done on the crate?
