Answer:
Explanation:
Given
Force 
time interval 
Impulse is given by 
For two significant Figure

Answer:
The time needed is 
Explanation:
From the question we are told that
The magnitude of the stimulated acceleration due gravity is 
The diameter of the spaceship is 
Generally the force acting on the spaceship is

Given that the spaceship is rotating it implies that the force experienced by the occupant is a centripetal force so

Thus

=> 
Generally the speed of this spaceship is mathematically represented as

=> ![v^2 = [\frac{2\pi}{T}] ^2](https://tex.z-dn.net/?f=v%5E2%20%20%3D%20%20%20%5B%5Cfrac%7B2%5Cpi%7D%7BT%7D%5D%20%5E2)
=> 
=> 
=> 
substituting values


Equal to 50
law of reflection: angle of incidence equals angle of reflection
