A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of 495.0 N on the rope which is inclined at 34.0° to the horizontal, and the floor exerts a horizontal force of 116.0 N that opposes the motion. Calculate the acceleration of the crate if its mass is 340.0 kg.
What would its acceleration be if its weight were 340.0 N?
