Question

How high would a 75 kg hiker have to climb to increase her potention by 12000 J

Answer 1

16.33m

Explanation:

Given parameters:

Mass of the hiker = 75kg

Potential energy = 12000J

Unknown:

Height = ?

Solution:

The potential energy is the energy at rest of a body.

   Potential energy =  mgh

m is the mass of the hiker

g is the acceleration due to gravity

h is the height

  The unknown is the height;

          Height = $\frac{Potential energy}{mg}$

           Height = $\frac{12000}{75 x 9.8}$ = 16.33m
