An astronaut has a mass of 68 kg, what is the weight of the astronaut on earth at sea level? What are the mass and the weight of the astronaut on the Moon, and on Mars? What is the ratio of the pressure exerted by the astronaut's shoe on Earth to Mars?
What will be an ideal response?
to solve this problem (gmoon = 1.6 m/s2, and gMars = 3.7 m/s2).
W = mg
The astronaut has a mass of 68 kg regardless of where he is. The weight of the
astronaut
Provided the shoe size is the same, the ratio of the pressure exerted by the
astronaut's shoe on earth to Mars is the same ratio as that of acceleration due to
gravity on earth to acceleration of gravity on Mars.
