Question

artificial satellite takes 90 minutes to complete its Revolution around Earth calculate the angular speed of satellite

Answer 1

time period of the satellite is T=90 min= 90 x 60 sec=5400 sec
angular speed ω = 2π/T = 2 x 1.414 / 5400 = 0.00116 rad/s

Answer 2

Answer:

The angular speed of satellite is 0.00116 rad/s.

Explanation:

Given that,

Time t = 90 minutes = 5400 sec

The angular speed is the change of the angular displacement with the time.

The angular speed is defined as:

$\omega = \dfrac{2\pi}{T}$

$\omega = \dfrac{2\times3.14}{5400}$

$\omega = 0.00116\ rad/s$

Hence, The angular speed of satellite is 0.00116 rad/s.
