If a hiker that weighs 600 newtons climbs a 50 meter hill, how much gravitational potential energy has the hiker gained?

The gravitational potential energy U is defined as the product of mass m, the acceleration of gravity g and the height of object h.

We do not have the mass of the hiker. But we know that its W weight is:

Where

So:

.

So:

J

The hiker has gained 30,000 J of energy

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

they should be similar or the same
