Answer :
We can calculate the potential energy using the formula
$$
PE = mgh,
$$
where
- $m$ is the mass,
- $g$ is the acceleration due to gravity, and
- $h$ is the height.
Given:
- $m = 25 \, \text{kg}$
- $g = 9.8 \, \text{m/s}^2$
- $h = 3 \, \text{m}$
Substitute the values into the formula:
$$
PE = 25 \times 9.8 \times 3.
$$
Calculating step-by-step:
1. First, multiply $9.8$ by $3$:
$$
9.8 \times 3 = 29.4.
$$
2. Then, multiply by $25$:
$$
25 \times 29.4 = 735.
$$
Thus, the potential energy is
$$
PE = 735 \, \text{Joules}.
$$
