Calculate the minimum velocity required by spacecraft to escape the earth's gravitational forces.

Define Earth's gravitational force

The escape velocity on the surface of earth is 11.2 km/s. If earth has mass 9 times the mass of Mars and radius equal to twice the radius of Mars, calculate the minimum velocity required by a projectile to escape the gravitational field of Mars.

If the earth has mass 9 times and radius twice that of the planet Mars, calculate the minimum velocity required by a rocket to pull out of the gravitational force of Mars. Escape velocity on the surface of the earth in 11.2 km//s

Calculate the minimum speed required by a rocket to pull out of the gravitational force of Mars. Given that the earth has a mass 9 times and radius twice of the planet Mars. Escape speed on the surface of earth is 11.2 km s^(-1) .

A particle of mass m is lying at the centre of a solid sphere of mass M and radius R . There is a turnel of negligible thickness, so that particle may escape. Find the minimum velocity required to escape the particle from the gravitational field of the sphere.

A particle of mass m is lying at the centre of a solid sphere of mass M and radius R . There is a turnel of negligible thickness, so that particle may escape. Find the minimum velocity required to escape the particle from the gravitational field of the sphere.

The International Space Stations (ISS), a habitable artificial satellite, is orbiting around earth at an altitude of 400 km. Calculate the additional velocity required to be given to escape the ISS from gravitational pull of earth.

If Earth has mass nine times and radius twice that of the planet Mars, calculate the velocity required by a rocket to pull out of the gravitational force of Mars. Take escape speed on surface of Earth to be 11.2km//s

Deduce an expression for the minimum velocity with which a rocket must be fired to escape earth's gravitational field.
