1. The problem statement, all variables and given/known data A man is pushing a 75 kg crate at constant velocity a distance of 12 m across a warehouse. He is pushing with a force of 225 N at an angle of 15° down from the horizontal. The coefficient of friction between the crate and the floor is 0.24. How much work did the man do on the crate? 2. Relevant equations 3. The attempt at a solution Fn = mg + 225sin15 = 794 Fnet = 217.33 - 190.5 = 26.83 26.83*12= 321 J I did solve the question, but there is one thing that I don't understand: How can the object have a net force (in this case, 26.83) and still move in constant velocity? Wouldn't it have a constant acceleration instead?
