The potential energy of a 25 kg bicycle resting at the top of a 3 m high hill is what?
Potential energy is the energy that is stored in an object due to its position relative to some zero position. It is calculated by the expression as follows:
PE = mgh
PE = 25 (9.8) (3)
PE = 735 J
Hope this answers the question. Have a nice day.
Explanation:
Potential energy is the energy obtained by a substance due to their position.
Mathematically, P.E = mgh
where m = mass
g = acceleration due to gravity = 9.8 m/s
h = height
Since it is given that mass is 25 kg and height is 3 m. Hence, calculate the potential energy as follows.
P.E = mgh
= \(25 kg \times 9.8 m/s \times 3 m\)
= 735 kg/s
Thus, we can conclude that potential energy for the given case is 735 kg/s.
