Question

Define critical velocity and escape velocity discuss the possibilities of orbits of satellite when horizontal velocity of projection is less than critical velocity and greater than escape velocity

Answer 1

Sorry i just know the defination :(

Answer 2

Critical Velocity - The velocity at which an object should travel to move out of gravitational pull of planet and move into space.

Escape Velocity - The minimum velocity at which an object should travel to avoid getting gravitational pulls from a planet.

When horizontal velocity of projection is less than critical velocity then object will not revolve around the planet and will fall back. This fall back will be in parabolic path.

When horizontal velocity of projection is greater than critical but than escape velocity, satellite will revolve in elliptical orbit.
