The speed of a satellite in a circular orbit around the Earth is 4,188 m/s.
<h3>Speed of the satellite</h3>
The speed of the satellite is calculated as follows;
v = √GM/r
where;
- M is mass of Earth
- r is radius of satellite
v = √[(6.67 x 10⁻¹¹ x 5.98 x 10²⁴) / (3.57 x 6.37 x 10⁶)]
v = 4,188 m/s
Thus, the speed of a satellite in a circular orbit around the Earth is 4,188 m/s.

The final velocity of the rock is 19.8 m/s
Explanation:
The motion of the rock is a free fall motion (subjected only to the force of gravity), with constant acceleration towards the ground. Therefore, we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the vertical displacement
For the rock in this problem,
u = 0 (initial velocity is zero)
s = 20 m (height of the cliff)
Solving for v,
