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
lawyer [7]

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
