Homework Statement

Which one of the quantities below has dimensions equal to [ML/T²]?

Homework Equations

a. mv
b. mv²
c. mv²/r
d. mvr
e. mv²/r²

The Attempt at a Solution

I know that ML/T² is for calculating force for circular motion (I believe)
Therefore after breaking it all down I come to the following conclusions

F = ma
F = m x (v1-v2)/t1-t2
THEREFORE Iam inclined to answer that c is the correct answer, but I am not sure if I am on the correct path, or in left field...
CAN ANYONE HELP ME?

The answer is C.

Velocity is just L/T. So V² equals (L/T)². R = L so one of the L's cancel and you are left with answer C.
