Question

in the perpemulcudi u.
An artificial satellite is moving in a circular orbit of radius
42250 km. Calculate its speed if it takes 24 hours to revolve
around the earth.
​

Answer 1

Answer:

11065.47 km/hr

Explanation:

Radius of Orbit = 42250 km  

Total Distance Traveled = 2$\pi$r = 2×(22/7)×(42250) = 265571.42 km

Total Time Taken = 24 hours

Speed = $\frac{Total Distance Traveled}{ Total Time Taken}$

            =   $\frac{ 265571.42 km}{24 hr}$ = 11065.47 km/hr
