Answer: The speed of a satellite in a circular orbit around the Earth with a radius 3.57 times the mean radius of the Earth is 4188.11 m/s.

Explanation: To find the answer, we need to know about the equation of motion of a satellite around earth.

<h3>What is the equation of motion of a satellite around earth?</h3>

We have gravitational force of attraction between the satellite of mass m and earth of mass M as,

$F_g=\frac{GMm}{r^2}$

The expression for centripetal force of,

$F_c=\frac{mv^2}{r} \\$

These two forces are equal for a satellite around earth.

$\frac{GMm}{r^2} =\frac{mv^2}{r} \\thus,\\v=\sqrt{\frac{GM}{r} }$

<h3>How to solve the problem?</h3>

Given that,

$r=3.57 R_E=3.57*6.37*10^3=22.74*10^3 km\\M=5.98*10^24kg\\G=6.67*10^{-11}Nm^2/kg^2$

Thus, the speed of the satellite will be,

$v=\sqrt{\frac{6.67*10^{-11}*5.98*10^{24}}{22.74*10^6m} } =4188.11 m/s$

Thus, we can conclude that the speed of satellite will be 4188.11 m/s.

How are velocity and displacement related?

Keith_Richards [23]

Velocity is the rate at which displacement changes with time. It is a vector, too. The average velocity over some interval is the total displacement during that interval, divided by the time. ... Speed is a scalar, which describes the total distance travelled by some object during some time interval. Plze mark me brainiest
