Almost. Very close. But don't forget about the direction. Ask yourself this: Is the gravitational force in the same direction as the y-component of displacement or is it in the opposite direction?
Another way of asking the same question, is the component of gravitational force that is...
1. An 8.3 kg crate is pulled 4.8 m up a 30 degree incline by a rope angled 18 degrees above the incline. The tension in the rope is 120 N and the crate's coefficient of kinetic friction on the incline is 0.24. How much work is done by tension, by gravity, and by the normal force? What is the...
