Question

The mass of the rock is 1220 kg. It had 400 J of potential energy as it sits on the hill. Calculate the height

Answer 1

Approximately 0.327 is the height.

Answer 2

The object is at a height of 0.0335 m

Step-by-step explanation:

First let's see what is the formula of gravitational potential energy

`E_p=m.g.h`

m= mass of the object

g= gravity (the value of gravity is a constant. Its value is approximately
`9.8m/s^2`)

h= height at which the object is in relation to zero

To calculate the height at which the object is enclosed, we clear the h of the formula

`E_p= m.g.h\\(E_p)/(m.g)=h`

Now we substitute the data in the formula

`(E_p)/(m.g)=h\\(400J)/(1220Kg.9.8(m)/(s^2) )= h\\0.0335m=h`

The object is at a height of 0.0335 m
