A person's energy output is being measured using a treadmill (see the diagram below). The angle of incline is 0 and the person walks a total distance d meters up the incline. For simplicity, treat this as if it was a continuous long slope. o a) Draw a diagram indicating the forces acting ON the person, such that the person is in equilibrium (not accelerating). The force of gravity on the person by Earth is shown. The hand is only used for balance so the force on the hand by the rail is negligible. o b) Assuming a long continuous walk on the treadmill, describe the energy transformations. Include the initial and final forms of energy and where or how changes occur. W-mg

I don't know what the answer to question b is 

1. A person's energy output is being measured using a treadmill (see the diagram below). The angle of incline is 0 and the person walks a total distance d meters up the incline. For simplicity, treat this as if it was a continuous long slope. o a) Draw a diagram indicating the forces acting ON the person, such that the person is in equilibrium (not accelerating). The force of gravity on the person by Earth is shown. The hand is only used for balance so the force on the hand by the rail is negligible. o b) Assuming a long continuous walk on the treadmill, describe the energy transformations. Include the initial and final forms of energy and where or how changes occur. W= mg
