As you know weight of an object is the product of the mass and the acceleration due to gravity
i.e W=m*g
where g is acceleration due to gravity which changes with the location.
and m is the mass of the object.
Assuming the object/body is in earth(at equator) we can get the mass of the body as m = W/g
= 38.5 N/9.8 m/square(s)
= 3.93 Kg

i just went over this in genral science. u divide the amount of newtons by 9.8 grams and u get the mass. one newton is equal to 9.8 grams. so the mass of 38.5N = 309285 give or take a gram or two. hope this helps. GOOD LUCK

F=ma <-- newton's law
force = mass * Acceleration
38.5 N is your force and you can assume your acc. is gravitational so if you divide 38.5N/9.8m/s^2 you can get the mass of your object

F = M * a
38.5 N is a force. On earth, all things accelerate at 9.81 m/s²
Therefore the mass is 38.5/9.81 = 3.92 N s²/m = 3.92 kg

weight = mass X acceleration due to gravity
38.5 = mass X 9.81 (all in MKS unit)
so, mass = 38.5/9.81 Kg = 3.92456 Kg = 3,924.56 Grams

W = mg
38.5 = m x 9.8
38.5/9.8 = m
m = 3.9286 kg
m=mass
g=gravitational gravity
w=weight

Is the object on earth? if so divide by 9.8N to get your mass in KG
