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 N on the rope, which is inclined at 38° to the horizontal, and the floor exerts a horizontal force of 125 N that opposes the motion. Calculate the acceleration of the crate if its mass is 331 kg and calculate the acceleration of the crate if its weight is 331 N.

The upward force the rope exerts is 450*sin38. The horizontal force is 450 cos38

Horizontal forces= mass*acceleation

450cos38 - 125- mass*acceleraiton

calcuate acceleration. Mass=weighcrate/g
