Explanation:
The force of kinetic friction on the block is defined as:
Where 
is the coefficient of kinetic friction between the block and the surface and N is the normal force, which is always perpendicular to the surface that the object contacts. So, according to the free body diagram of the block, we have:
Replacing this in the first equation and solving for :
"An object weighs about two times as much on Jupiter as on Neptune." Hope this helps :)
