A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of 450.0 N on the rope which is inclined at 38.0° to the horizontal, and the floor exerts a horizontal force of 124.0 N that opposes the motion. Calculate the acceleration of the crate if its mass is 400.0 kg. Assume positive is to the right and up. What would its acceleration be if its weight were 400.0 N?
