Answer:

Height, h = 8.163 meters

Step-by-step explanation:

Given the following data;

Mass = 10kg

Potential energy = 800J

We know that acceleration due to gravity is equal to 9.8m/s²

To find the height of the hill;

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;


P.E = mgh

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the equation, we have;

800 = 10*9.8*h

800 = 98h

Height, h = 800/98

Height, h = 8.163 meters
