Answer :

To find the potential energy of the bicycle, you can use the formula for gravitational potential energy:

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

Here's how you can calculate it step-by-step:

1. Identify the mass (m): The mass of the bicycle is given as 25 kg.

2. Identify the height (h): The height of the hill is 3 meters.

3. Identify the acceleration due to gravity (g): The standard gravity on Earth is approximately 9.81 m/s².

4. Substitute these values into the formula:

[tex]\[ \text{PE} = 25 \, \text{kg} \times 9.81 \, \text{m/s}^2 \times 3 \, \text{m} \][/tex]

5. Calculate the result: After performing the multiplication, the potential energy is 735.75 joules.

Conclusion:
The potential energy of the 25 kg bicycle at the top of a 3 m high hill is 735.75 Joules.
