Question

If a 0.5 kg pair of running shoes would weigh 11.55 Newton’s on Jupiter, what is the strength of gravity there?

Answer 1

The weight of an object is given by

`F=mg`
where m is the mass of the object, while g is the strength of the gravity (which corresponds to the gravitational acceleration of the planet).

In our problem, the shoes have a mass of m=0.5 kg, and their weight is F=11.55 N. So, we can re-arrange the previous formula to find the value of g:

`g= (F)/(m)= (11.55 N)/(0.5 kg)=23.1 N kg^(-1)`
and this is the strength of the gravity on Jupiter's surface.
