Question

A speed (L/T) divided by a force (ML/T2) yields?

Answer 1

is it T/M^-1?

Answer 2

Just to be clear:

L = Length
T = Time
M = Mass

So a speed divided by a force is:

\[\frac{\frac{L}{T}}{\frac{ML}{T^2}}=\frac{L}{T}\frac{T^2}{ML}\]

I obtained the right hand side by the rule of dividing fractions ("invert the denominator and multiply by the numerator").

Now we cancel factors...
