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`

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.

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) .

The moon has a mass of (1)/(81) that of the earth and radius of (1)/(4) that of the earth. The escape speed from the surface of the earth is 11.2 km // s. The escape speed from surface of the moon is-

Graviational acceleration on the surface of plane fo (sqrt6)/(11)g. where g is the gracitational acceleration on the surface of the earth. The average mass density of the planet is (2)/(3) times that of the earth. If the escape speed on the surface of the earht is taken to be 11 kms^(-1) the escape speed on teh surface of the planet in kms^(-1) will be

Jupiter has a mass 320 times that of the earth and its readius is 11.2 times that of the earth. Determine the escape velocity from the surface of jupiter, given that the escape velocity from the surface of earth is 11.2 km s^(-1) .

A man can jump up to a height of h_(0)=1m on the surface of the earth. What should be the radius of a spherical planet so that the man makes a jump on its surface and escapes out of its gravity? Assume that the man jumps with same speed as on earth and the density of planet is same as that of earth. Take escape speed on the surface of the earth to be 11.2 km/s and radius of earth to be 6400 km.

The mean diameters of Mars and Earth are 6.9 xx 10^3 km and 1.3 xx 10^4 km, respectively. The mass of Mars is 0.11 times Earth's mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b) What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?

A planet has a mass 120 times that of earth and radius is 5 times the radius of earth. What is the escape velocity at this planet if the escape velocity at earth's surface is 11.2 km s^(-1) .
