# Physics - Classical Mechanics

Not what you're looking for?

A student could either pull or push, at an angle of 300 from the horizontal, a 50-kg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.20. The crate is to be moved a horizontal distance of 15 m.

(a) Compared with pushing, pulling requires the student to do
(1) less, (2) the same, or (3) more work.

(b) Calculate the minimum work required for both pulling and pushing.
