Answer:
f = 1.96 revolutions per minute
Explanation:
The formula for the the frequency of revolution of a satellite, to develop an artificial gravity, with the help of centripetal acceleration is given as follows:
f = (1/2π)√(ac/r)
where,
f = frequency of rotation = ?
ac = centripetal acceleration= apparent gravity or artificial gravity = 2.2 m/s²
r = radius of station or satellite = diameter/2 = 104 m/2 = 52 m
Therefore,
f = (1/2π)√[(2.2 m/s²)/(52 m)]
f = (0.032 rev/s)(60 s/min)
<u>f = 1.96 revolutions per minute</u>
The question is how far not how for
Answer:
101.1 m
Explanation:
From the kinematics equations
s=ut-0.5gt^{2} but since u=o and the negative implies the distance is downwards then
s=0.5gt^{2} where s is the distance, u is initial speed, t is time, g is acceleration due to gravity
s=0.5*9.81*4.54^{2}=101.099898
\approx 101.1 m
