An object of mass 95 kg is at a height of 36 m. What is its potential energy?

To determine the potential energy of an object at a given height, the formula used is:

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h)

In this calculation, the mass (m) of the object is 95 kg, the height (h) is 36 m, and the standard gravitational acceleration (g) is approximately 9.81 m/s².

Plugging in the values:

PE = 95 kg × 9.81 m/s² × 36 m

Calculating this step by step:

1. First, calculate the product of mass and gravitational acceleration:

95 kg × 9.81 m/s² = 931.95 N (Newton)

2. Next, multiply this result by the height:

931.95 N × 36 m = 33553.2 Joules

3. Convert joules to kilojoules:

33553.2 J ÷ 1000 = 33.55 kJ

Thus, the potential energy of the object is 33.55 kJ. This confirms that the choice indicating this value is indeed the correct answer. Potential energy directly relates to an object’s position in
