A 67 kilogram crate is dragged across a floor by pulling on a rope attached to the crate and inclined 15 degree above the horizontal.
(a) If the coefficient of static friction is 0.48, find what minimum force magnitude is required from the rope to start the crate moving?
N
(b) If µkin = 0.33, find what is the magnitude of the initial acceleration of the crate?
m/s2
