Question

An alien with a mass of 71 kg is floating 670 m from his spaceship's center of mass. His ship's mass is about 500,000 kgWhat is the gravitational attraction between the alien and his ship?

Answer 1

5.28 x 10⁻⁹N

Step-by-step explanation:

Given parameters:

Mass of alien = 71kg

Distance = 670m

Mass of ship = 500000kg

Unknown:

Gravitational attraction = ?

Solution:

The gravitational attraction can be found using the Universal gravitation law proposed by Newton;

Fg =
`(G x mass 1 x mass 2)/(d^(2) )`

G is the universal gravitation constant = 6.67 x 10⁻¹¹

d is the distance

Fg is the gravitational attraction

Fg =
`(6.67 x 10^(-11) x 71 x 500000 )/(670^(2) )` = 5.28 x 10⁻⁹N
