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 68 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 15o 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 ยตk = 0.35, what is the magnitude of the initial acceleration of the crate?
