A horizontal force of 24 N is being applied to a box on a level surface.
The box is accelerating at the rate of 2.0 m/s2 against a frictional force
of 14 N. What is the mass of the box?
Select one:
12 kg
5.0 kg
19 kg
7.0 kg

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
