Question

‏What is the potential energy in joules of a 12 kg ( mass ) at 25 m above a datum plane ?

Answer 1

The potential energy of a 12 kg mass at a height of 25 m above a datum plane is 2940 joules.

The potential energy of an object can be calculated using the formula:

Potential energy = mass * gravity * height

Given:

Mass = 12 kg

Gravity = 9.8 m/s^2 (approximately)

Height = 25 m

We can substitute the values into the formula to find the potential energy:

Potential energy = 12 kg * 9.8 m/s^2 * 25 m

Potential energy = 2940 joules

Therefore, the potential energy of a 12 kg mass at a height of 25 m above a datum plane is 2940 joules.

Answer 2

E = 2940 J

Step-by-step explanation:

It is given that,

Mass, m = 12 kg

Position at which the object is placed, h = 25 m

We need to find the potential energy of the mass. It is given by the formula as follows :

E = mgh

g is acceleration due to gravity

`E=12* 9.8* 25\\\\E=2940\ J`

So, the potential energy of the mass is 2940 J.
