To what height should a body weighing 300 g be thrown in order for it to acquire a potential energy of 12J?

In order to find at what height it is necessary to throw a body weighing 300 grams so that it acquires a potential energy of 12 J, we will apply the formula to calculate the potential energy of a body raised above the ground.

Let’s remember the formula:

Ep = m * g * h.

The potential energy of a body raised above the ground is equal to the product of the body’s mass by the acceleration of gravity g = 10 m / s ^ 2 (constant value) and by the height.

Let us express the height from the formula:

h = Ep / m * g = 12 J / 0.3 kg * 10 m / s ^ 2 = 12/3 = 4 m.

Answer: 4 m.
