Question

A crate of 50.0 kg mass containing new physics textbooks is dragged by enthusiastic physics students a distance of 30.0 m along a 25o incline to a physics lab. The students maintain a constant pull of magnitude 250 N applied to the crate by means of a rope parallel to the incline.
a. Calculate the work done by each force on the crate. Ignore friction.
WA = A delta(x) cos (0) = (250 N)(30.0m) = 7500 J
Ww = (mg) ?delta(x) cos (theta) = (50.0 kg)(9.81 m/s2)(30.0m)cos (115) = -6219 J
Wn = n delta(x) cos (90) = 0
