Question

What is the gravitational potential energy of a 2100 kg car at the top of an 18 m parking garage?

Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Gravitational Potential of an object with mass m, and height of h metre is :

`\qquad \sf  \dashrightarrow \:mgh`

Now, if the mass of object is 2100 kg, height of 18 m is placed in there, then it's gravitational potential energy is ~

`\qquad \sf  \dashrightarrow \:2100 * 10 * 18`

`\qquad \sf  \dashrightarrow \:378000 \: \: joules`

`\qquad \sf  \dashrightarrow \:3.78 * 10 {}^(5) \: \: joules`
