Detailed explanation-1: -The escape velocity of Mars is 4.25 km. s. The escape velocity of Earth is 11.19 km/s.
Detailed explanation-2: -Escape velocity is the minimum velocity that a body must attain to escape a gravitation field completely. Jupiter has the highest escape velocity among planets. This is because Jupiter has the highest mass. The escape velocity of Jupiter is 59.5 km/s.
Detailed explanation-3: -At Earth’s surface, if atmospheric resistance could be disregarded, escape velocity would be about 11.2 km (6.96 miles) per second.
Detailed explanation-4: -Thus, the ratio of the escape speed of Mars to the Earth is 0.45.
Detailed explanation-5: -Since, acceleration due to gravity on moon is one-sixth of that on Earth, thus the escape velocity on the Moon is lees than that on the Earth.
