Question

2) Calculate the gravitational potential energy that a parachutist has just as he

Answer 1

Answer:

The gravitational potential energy of the parachutist is 3,528,000 J

Explanation:

Gravitational Potential Energy

It's the energy stored in an object because of its height in a gravitational field.

It can be calculated with the equation:

U=m.g.h

Where:

m = mass of the object

h  = height with respect to a fixed reference

g  = acceleration of gravity, usually taken as $9.8 m/s^2$.

The parachutist has a mass of m=120 kg and he jumps at a height of h= 3,000 m. Computing the gravitational potential energy:

U = 120 * 3,000 * 9.8

U = 3,528,000 J

The gravitational potential energy of the parachutist is 3,528,000 J
