Question

why is gravity not negative? (-9.8 m/s^2)

First: we find the mass of the man by using the following equation:
fg = mg
Solving for (m),
fg 900
= 91.8 kg
9.8
m =
Then: we can find the weight of the man on Jupiter using the value of mass
we found:
fg.J
= mgj = 91.8 × 25.9 = |2.38 × 10³ N
fg.J
|2.38 × 10³ N

If a man weighs 900 N on the Earth, what would he weigh on
Jupiter, where the free-fall acceleration is 25.9 m/s²?
