At the end of a bike ride up a mountain, Chris was at an elevation of 500 meters above where he started. If Chris's mass is 60kg
, by how much did his potential energy increase?
1 answer:
294000J
Explanation:
Given parameters:
Height of hill = 500m
Mass of Chris = 60kg
Unknown:
Potential energy increase = ?
Solution:
Potential energy is the energy by virtue of the position of a body.
Potential energy = mgh
m is the mass of the bike
g is the acceleration due to gravity
h is the height
At the base of the hill,
P.E = mgh = 60 x 9.8 x 0 = 0J
At the top:
P.E = mgh = 60 x 9.8 x 500 = 294000J
Potential energy increase = 294000J - 0J = 294000J
