Question

A 65 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 12° above the horizontal. (a) If the coefficient of static friction is 0.57, what minimum force magnitude is required from the rope to start the crate moving? (b) If μ_k = 0.33, what is the magnitude of the initial acceleration (m/s^2) of the crate?
