The mass of an astronaut is 72kg.
(a) what is his weight on earth ( taking g to be 10N/kg) ?
(b) if the astronaut is on the moon's surface where the acceleration due to gravity is one-sixth on the earth , calculate
(I) the mass
(ii) the weight of the astronaut

Thanks for helping me out , good deeds will be return :)

  1. (a) Weight = Mass * g = 720 Newtons

    (i) mass M stays the same at 72 kg
    (ii) 1/6 of 720 Newtons = ___
