A body weighing 3 kg falls freely within 2 s. Determine the potential energy of the body.

To solve the problem, we need to use the fall height formula:
h = g * t ^ 2/2;
And the formula for potential energy:
Ep = m * g * h = m * g * g * (t ^ 2) / 2;
En = m (gt) ^ 2/2;
Let’s substitute the value from the problem into the formula:
En = 3 * (10 * 2) ^ 2/2;
Ep = 600 J.
Answer: En = 600 J.
