An aeroplane is moving with horizontal velocity u at height h . The velocity of a packet dropped from it on the earth's surface will be ( g is acceleration due to gravity)

As we move far from the earth's surface the magnitude of acceleration due to gravity ......

At a height equal to earth's radius, above the earth's surface, the acceleration due to gravity is

An aeroplane is moving with a velocity u. It drops a packet from a height h. The time t taken by the packet in reaching the ground will be

Let g be the acceleration due to gravity on the earth's surface.

The escape velocity of a projectile from the earth.s surface is given by the formula (R to radius of the earth and .g. is acceleration due to gravity)

An earth satellite of mass m revolves in a circular orbit at a height h from the surface of the earth. R is the radius of the earth and g is acceleration due to gravity at the surface of the earth. The velocity of the satellite in the orbit is given by
