Question

The speed of the revolution of an artificial satellite is 8km/s what will be the escape velocity

Answer 1

Escape velocity = √2 × orbital velocity

Escape velocity = √2 × 8 = 11.314 km/s

Answer 2

Given,

The orbital velocity of artificial satellite = 8 km/s

To Find,

The escape velocity of the satellite.

Solution,

In space mechanics, the speed of escape or the speed of escape is the minimum speed required for a free object, which does not continue to escape the influence of the gravitational force of the main body, thus reaching an infinite distance from it. It is often referred to as the right speed, you can ignore the collision of the atmosphere.

The formula for calculating the escape velociy is

Escape velocity = √2*orbital velocity

Escape velocity - √2*8 = 11.31 km/s

Hence, the escape velocity of the satellite is 11/31 km/s.
