Question

How much gravitational energy does a 65 kg skydiver have 650 m up in the sky?

Answer 1

G.P.E = 414050 Joules or 414.05 Kilojoules

Step-by-step explanation:

Given the following data;

Mass = 65 kg

Height = 650 m

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

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

`G.P.E = mgh`

Where;

• G.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;

`G.P.E = 65 * 9.8 * 650`

`G.P.E = 414050`

G.P.E = 414050 Joules or 414.05 Kilojoules.
