Find the hiker’s gravitational potential energy if the cliff is 60m high (show the equation, show your work and answer with units.)

Here we do not have the mass of the hiker, but we can answer it for a more general case, suppose that the mass of the hiker is M

For lifted objects, the only force acting on them is the force of gravity, and this force is equal to the mass times the gravitational acceleration, or:

Fg = M*g where g is equal to 9.8m/s^2

Now, the potential energy also depends on the distance that the object will move is it starts to fall, this distance h is the distance of the cliff for example, so we have:

PE = M*g*h

where the value of g is already known and the value of h is 60m

the answer is a. at the equator

spare some change and give it to the poor
