Answer:
The angular velocity is 0.40090415 rad/sec.
Explanation:
Given that,
Height = 30 feet
Rotating rate =55,145 rev/day
We need to calculate the angular velocity
[tex]1\ revolution = 2\pi[/tex]
So, [tex]1\ revolution /sec=\dfrac{2\pi}{60\times60\times24}\ rad/sec[/tex]
[tex]1\ revolution /sec=7.27\times10^{-6}\ rad/sec[/tex]
[tex]55,145\ revolution /sec=55,145\times7.27\times10^{-6}\ rad/sec[/tex]
[tex]55,145\ revolution /sec=0.40090415\ rad/sec[/tex]
Hence, The angular velocity is 0.40090415 rad/sec.
