Question

What would the weight of an astronaut be on Neptune if his mass is 68 kg and acceleration of gravity of Neptune is 11.15 m/s^2?

Answer 1

Weight = Mass of object * Gravity of experimented place
Here, m = 68 Kg
g' = 11.15 m/s²

Substitute their values,
w = 68 * 11.15
w = 758.2 N

In short, Your Answer would be 758.2 Newtons

Hope this helps!
