Suppose a skydiver (mass =100kg) is falling towards the earth. when the skydiver is 80 m above the earth he is moving at 60 m/s at this point calculate the skydivers gravitational potential energy

78400 J

Explanation:

The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field.  That is why this energy depends on the relative height of an object with respect to some point of reference and associated with the gravitational force.  

In the case of the Earth, in which the gravitational field is considered constant, the value of the gravitational potential energy will be:  

Where:

is the mass of the skydiver

the acceleration due gravity

the height of the skydiver

Hence:
