Answer :

To find the potential energy of a bicycle resting at the top of a hill, we need to use the formula for gravitational potential energy:

[tex]\[ \text{Potential Energy} (PE) = \text{mass} \times \text{gravitational acceleration} \times \text{height} \][/tex]

Where:
- The mass of the bicycle is 25 kg.
- The gravitational acceleration is approximately 9.8 meters per second squared (m/s²) on the surface of the Earth.
- The height of the hill is 3 meters.

Substituting these values into the formula:

[tex]\[ PE = 25 \, \text{kg} \times 9.8 \, \text{m/s}^2 \times 3 \, \text{m} \][/tex]

[tex]\[ PE = 735 \, \text{Joules} \][/tex]

Therefore, the potential energy of the bicycle at the top of the hill is 735 Joules. The correct answer is 735 J.
