Answer: 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.
