a worker drags a 310 kg crate at a constant velocity of 3 m/s, 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 degrees to the horizontal, and the floor has a coefficient of friction of 0.4. What is the tension in the rope? What is the acceleration of the crate?
