Using dimensional analysis, we can calculate the units of b by rearranging the equation F = bv. The units of force are kg*m/s^2, and the units of velocity are m/s. Therefore, the units of b must be kg/s in order for the units to work out. None of the other choices have these units.

In the Equation F = Bv,F Is the Force on an Object
