Question

An object of mass 1 kg has a potential energy of 20 J at a certain height above the ground. Find out the height of the with respect to the ground.(g=10m/s^2)​

Answer 1

Answer:

As we know,

Potential energy = mgH.

Given mass (m)= 1kg

Given g (acceleration due to gravity)= 10m/s^2

Given Potential energy = 20 J

So, calculate h.

Therefore,

$20 = 1\times10\times h \\20 = 1 \: \times 10\times h \\20 = 10 \times h \: \\ so \: h = \frac{20}{10} \\ h = 2.$

Therefore, height= 2 m.
