Answer:
Explanation:
Given that,
Initially, the spaceship was at rest, u = 0
Final velocity of the spaceship, v = 11 m/s
Distance accelerated by the spaceship, d = 213 m
We need to find the acceleration experienced by the occupants of the spaceship during the launch. It is a concept based on the equation of kinematics. Using the third equation of motion to find acceleration.
So, the acceleration experienced by the occupants of the spaceship is 
.
This the answer <span>Often, a law can be expressed in the form of a single mathematical equation. Laws and theories are similar in that they are both scientific statements that result from a tested hypothesis and are supported by scientific evidence. ... A theory, in contrast, is a less concise statement of observed phenomena. i hope this help </span>
Answer:
Since the bar cannot translate, linear momentum is not conserved
Explanation:
By conservation of the angular momentum:
Lo = Lf
where
; 
; d=1.6m; L=3m; 
; 
; 
Solving for 
:
Replacing the values we get:
Since the bar can only rotate (it canno translate), only angular momentum is conserved.
