Question

On Earth a fit astronaut without a space suit and life support pack can leap straight up and leave the ground with an initial vertical velocity of about voy = 2.4 m/s and rise to a height of about h = 0.24 m above the point where he first loses contact with the ground. On the other hand, an astronaut on the moon is burdened with a space suit and life support pack to protect him from the rarified atmosphere and extreme temperatures. This gear weighs about 180 lbs on Earth. Under these conditions do you predict the Astronaut

Explanation / Answer

astronaut vertical velocity is more on the moon than on the earth because in spite of heavy space suit the acceleration due to gravity acting on the astronaut vertically downward is one sixth on moon than on earth so less gravitational force acts on the astronaut hence its velocity is more on moon Overall height of an astronaut jump on the moon is more than the height of his jump on the earth because of less gravitational force acting on the astronaut on the moon than on earth
