The gravitational differences between the earth and Mars is a factor that engineers and scientists must consider before sending an astronaut to the “Red Planet.”
(a) What is the acceleration due to gravity on Mars?
(b) If an 85.0-kg astronaut landed on Mars, how much would the astronaut weigh there compared to his weight on the earth?
(c) Based on the acceleration due to gravity on Mars, what might happen to the strength of the astronaut’s muscles while the astronaut is away from earth?
