The potential energy of a 25 kg bicycle resting at the top of a 3 m high hill is
j. (gravity= 9.8 m/s)

The potential energy of the bicycle is 735 joules.

Explanation: The potential energy of the bicycle can be calculated as:

U = W*h

where W is the weight of the bicycle, and h is the height at where the bicycle is initially:

W = 25kg*9.8m/s^2  = 245 N

and h= 3m

U = 245N*3m = 735N*m = 735 J

So the potential energy of the bicycle while resting is 735 joules.
