An astronaut's pack weighs 10.8 N when she is on earth but only 4.15 N when she is at the surface of moon.
Part A
What is the acceleration due to gravity on this moon?
Part B
What is the mass of the pack on this moon?
here,
weight on earth , we = 10.8 N
and weight at the moon surface , Wm = 4.15 N
A)
let the accelration due to gravity on moon be g'
g'/g = mg'/mg= wm /we
g'/g = 4.15 /10.8
g' = 9.8 * 4.15 /10.8 = 3.77 m/s^2
the accelration due to gravity on moon is 3.77 m/s^2
B)
the mass of the pack , m =
wm/g' = 4.15/3.77 = 1.1 kg
the mass of the pack on moon is 1.1 kg
