Question

define circular velocity of a satellite revolves around a planet of radius 42000 km calculate its speed in 24 hours. It's metre per second​

Answer 1

In uniform circular motion

s=2πr/t where s is distance and t is time.

so,s=2X22/7X420000/24

s=264000/24

s=11000 km h^-1

To convert in m/s divide the value by 3600

so,

110000 X 1000/3600

=3055.5m s^-1
