I can't seem to find anything on how to calculate this in my physics book. I see how to find work done against anything else but not that.
1) Pete slides a crate up a ramp at an angle of 30.6degrees by exerting a 130 n force parallel to the ramp. the crate moves at a constant speed. The coefficient of friction is 0.16. How much work has been done against gravity when the crate is raised a vertical distance of 1.78m? Answer in units of J.
2) A cart loaded with bricks has a total mass of 24.7 kg and is pulled at constand speed by a rope. The rope is inclined at 27.9degrees above the horizontal and the cart moves 20.3 m on a horizontal floor. The coefficient if kinetic friction between ground and cart is 0.754. The acceleration of gravity is 9.8 m/s^2. HOw much work is done on the cart by the rope? Answer in units of J.
3) Karen has a mass of 51.6 kg as she rides up the escalator at Woodley Park station of the Washington DC Metro. Karen rode a distance of 52.4 nm tge kibgest escalator in the free world. The acceleration of gravity is 9.8 m/s^2. How much work did the escalator do on Karen if it has an inclination of 27.4degrees. Inswer in units of J.
