Honors earth science hw help!?

Question

the gravity of jupiter is 2.5 times that of the earth.

how much would a 60kg astronaut weigh if she could land on jupiter?

mow much mass would she have?

i think she would weig 24kg but will someone please tell me how to calculate the mass?

Answer 1

Earth's gravity is 9.81m/s^2.  If Jupiter's gravity is 2.5 times that of the earth, then Jupiter's gravity would be:

9.81x2.5 = 24.52m/s^2

Since weight=mass*gravity, plug in the values to get:

weight= 60kg * 24.52 m/s^2 =1471.5 N  (Newtons)

Mass is the same regardless of gravity.  ie, the astronaut's mass on Jupiter is 60kg, same as on Earth.
