Homework Statement
a 46.0kg child cycles up a large hill to a point that is vertical distance of 5.25m above the starting position find:
a.) The change in the childs gravitational potential energy
b.) The amount of work done by the child against gravity
Homework Equations
delta Eg=mg delta h?
W=delta Eg-g?
The Attempt at a Solution
delta Eg=(46.0kg)(9.80m/s2)(5.25m)
delta Eg=2366.7 J {This number seems too high though, and it wouldn't be the change. I don't know how to get that}
W=2366.7-9.80
W=2356.9J
