A 68.0 kg crate is dragged across a floor to the right by pulling on a rope attached to the crate and inclined 15.0° above the horizontal. (a) If the coefficient of static friction is 0.500, what minimum force magnitude is required from the rope to start the crate moving? (b) If the coefficient of kinetic friction is 0.350, what is the magnitude of the initial acceleration of the crate?
