The potential energy of a ball at a height of 1.2 m is 6 joules. Find the mass of the ball.

Given:

Wpotential = 6 Joules – potential energy of the ball;

h = 1.2 meters – the height at which the ball is located;

g = 9.8 Newton / kilogram – acceleration of gravity.

It is required to determine m (kilogram) – the mass of the ball.

To determine the mass of the ball, you need to use the following formula:

W potential = m * g * h, hence:

m = W potential / (g * h) = 6 / (9.8 * 1.2) = 6 / 11.8 = 0.5 kilograms (500 grams).

Answer: The mass of the ball is 0.5 kilograms (500 grams).
