Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine par…
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the d…

Question

A cart is loaded with a brick and pulled at constant speed along up a hill that is has a slope of 0.01 (1 meter rise for 100 meters of run). If the mass of the loaded cart is 10.0 kg and the height of the hill is 100 meters, then what is the potential energy of the loaded cart at the height of the hill? If I take a short cut up the hill which has a slope that is 0.2 and I get to the top in half the time have I done more or less work? And have I used more or less power?
