zephyr141 · Answer

$$w=m*g$$so since he's 1040N on earth you have to use the following equation to find his mass.$$m=\frac{w}{g}$$so plug the stuff that relates to earth into the second equation to find his mass then plug that mass into the first equation and use the given acceleration due to the gravity of Jupiter for g.

The acceleration of Gravity on Earth is 9.8 m/s^2, The acceleration of Gravity for Jupiter is 25.9 m/s^2.
   F = m a but as @zephyr141 labeled them, Weight (a force) = m (of the person) times g (the acceleration of the planet you are considering). Use the equations as they were rearranged to find the man's mass (a constant no matter where he is - Earth, Jupiter, space, etc.) and then go back to w = m g(Jupiter) ro find out what he weighs there.
