Orbital velocity of a satellite in its orbit (around earth) of radius r is v. It collides with another body in its orbit and comes to rest just after the collision. Taking the radius of earth as R, the speed with which it will fall on the surface of earth will be :

A satellite is orbiting the earth in a circular orbit of radius r . Its

A satellite is orbiting the earth in a circular orbit of radius r . Its

The orbital velocity of a satellite very near to the surface of earth is v. What will be its orbital velocity at an altitude 7 times the radius of the earth?

The orbital velocity of a satellite very near to the surface of earth is v. What will be its orbital velocity at an altitude 7 times the radius of the earth?

Critical velocity of a satellite orbiting around the earth (radius R) at a distance of 8 R from the surace is 2.5 km/s. Critical velocity of another satellite orbiting at a height of 15 R from the surface is

A satellite is orbiting around earth with its orbit radius 16 times as great as that of parking satellite. What is the period of this satellite.

An artificial satellite is moving in a circular orbit around the earth with a speed of equal to half the magnitude of escape velocity from earth. If the satellite is stopped suddenly in its orbit and allowed to fall freely on the earth. Find the speed with which it hits the surface of earth. Given, M=mass of earth & R =Radius of earth
