Question

Assuming Luke has a mass of 90Kg how much potential energy does he have just as he leaves the plane 7620 meters up? Explain how you know.

Answer 1

Answer : P = 6858 KJ

Explanation :

Mass of Luke, m = 90 Kg

Height, h = 7620 m

Acceleration due to gravity, g = $10\ m/s^2$

Gravitational potential energy, P = $m\times g\times h$

So, P = $90\times 10\times 7620$

P = 6858 KJ

Hence, the potential energy is 6858 KJ.
