Question:

A 68 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 15^o above the horizontal.

(a) If the coefficient of static friction is 0.50, what minimum force magnitude is required from the rope to start the crate moving?

(b) If µ_k = 0.35, what is the magnitude of the initial acceleration of the crate?
