Aworker drags a crate across a factory floor by pulling on a rope tied to the crate. the worker exerts a force of magnitude f = 450 n on the rope, which is inclined at an upward angle θ = 38° to the horizontal, and the floor exerts a horizontal force of magnitude f = 125 n that opposes the motion. calculate the magnitude of the acceleration of the crate if (a) its mass is 310 kg and (b) its weight is 310 n
