A man of mass 50 kg starts moving on the earth and acquires speed of 1.8 m/s. With what speed does the earth recoil? Mass of earth = 6xx10^24kg.

A man of mass 50 kg starts moving on the earth and acquires speed of 1.8 m/s. with what speed does the earth recoil? Mass of earth = 6xx10^24kg.

A man of mass 50 kg starts moving on the earth and acquires speed of 1.8 m/s. with what speed does the earth recoil? Mass of earth = 6xx10^24kg.

A man of mass 50 kg starts moving on the earth and acquires speed of 1.8 m/s. with what speed does the earth recoil? Mass of earth = 6xx10^24kg.

A satellite is revolving around the earth at a height of 600 km. find The speed of the satellite. Radius of the earth =6400 km and mass of the earth =6xx10^24kg .

Find the radius of the circular orbit of a satellite moving with an angular speed equal to the angular speed of earth's rotation. Mass of the earth =6xx10^24kg

If the escape velocity of a planet is 3 times that of the earth and its radius is 4 times that of the earth, then the mass of the planet is (Mass of the earth = 6 xx 10^24 kg )
