Question

A 10 kg rock is at the top of 20 meter tall hill what is the energy does it have

Answer 1

Energy, E = 1960 J

Step-by-step explanation:

We have,

Mass of the rock is 10 kg

It is at the top of 20 m tall hill

The rock will have a potential energy. The energy possessed by the rock is called gravitational potential energy. It is given by :

E = mgh

g is acceleration due to gravity

`E=10* 9.8* 20\\\\E=1960\ J`

So, the energy possessed by the rock is 1960 J.
