Question

A helicopter is flying 8 kilometers above the ground. It has a gravitational potential energy of 376 Joules. What would the mass be?

Answer 1

0.0048kg

Step-by-step explanation:

Given parameters:

Height of flight = 8km = 8000m

Gravitational potential energy = 376J

Unknown:

Mass = ?

Solution:

To solve this problem;

Gravitational potential energy = mgh

m is the mass of the body

g is the acceleration due to gravity

h is the height of the helicopter

Insert the parameters and solve;

376 = m x 9.8 x 8000

376 = 78400m

m = 0.0048kg
