Question

a 70 kg persom travels to a planet where he waighs 1,700 newtons what is the value of g on that planet

Answer 1

F = ma
F = mg
(1700 N) = (70kg)g
g = (1700N)/(70kg)
g = 24.285714285714285714285714285714 N/kg = 24.285714285714285714285714285714 m/s^2

The following is not part of the answer to your question but is additional information.:
(24.285714285714285714285714285714 m/s^2)/(9.8 m/s^2) = 2.4781341107871720116618075801749 which means that the gravity on that other planet is about 2.5 times as strong as that as our planet Earth.
