Question

9. An astronaut of mass 90 kg walks in space outside her spaceship and receives a 30-N force from a nitrogen spurt gun. What acceleration does she experience?

Answer 1

acceleration is equal to force / mass
thus 30/90 is 0.33 m/s^2

Answer 2

Acceleration of the spurt gun is 0.33 m/s^2

Step-by-step explanation:

Given that,

Mass of the astronaut is 90 kg

Force received from a nitrogen spurt gun is 30 N

To find :

Acceleration received to the astronaut.

Solve :

Let a is the acceleration. It can be found using the second law of motion. The formula of force is given by :

`F=ma`

`a=(F)/(m)`

`a=(30\ N)/(90\ kg)`

a = 0.33 m/s^2

Therefore, the acceleration experienced by the astronaut is 0.33 m/s^2
