A man can jump `1.5m` high on earth. He can jump on a planet to a height of `3 xx x` metre. The density of planet is one quarter that of the earth and whose radius is one third of the earth. What is the value of `x`?

A man can jump 1.5m on the Earth. Calculate the approximate height he might be able to jump on a planet whose density is one-quarter that of the Earth and whose radius is one-third that of the Earth.

A man can jump 2.0 m high on the earth. Up to what height he can jump on a planet whose density is one quarter that of Earth and radius in one-third of the Earth's radius.

If the density of the planet is double that of the earth and the radius 1.5 times that of the earth, the acceleration due to gravity on the planet is

If the density of the planet is double that of the earth and the radius 1.5 times that of the earth, the acceleration due to gravity on the planet is

A man can jump six times as high on the moon as that on the earth. Justify.

The maximum vertical distance through which a fully dressed astronaut can jump on the earth is 0.5 m . If mean density of the Moon is two-third that of the earth and radius is one quarter that of the earth, the maximum vertical distance through which he can jump on the Moon and the ratio of the time of duration of the jump on the Moon to hold on the earth are
