Acceleration in terms of velocity and radius??! 1. The problem statement, all variables and given/known data Which one of the quantities below has dimensions = [(ML)/(T^2)] MV MV^2 (MV^2)/R MRV (MV^2)/(R^2) 2. Relevant equations My physics textbook defines 3 basic dimesions: M = Mass. T = Time. L = Length. 3. The attempt at a solution I know that [(ML)/(T^2)] = mass x acceleration. Each of the 5 possible answers has an "M" which is mass. Therefore, I'm assuming that acceleration must be expressed in terms of "R" (which I think might be radius) and V (which I think is velocity). Is this line of thinking correct? As in, can acceleration be expressed in terms of Velocity and Radius? Or is this line of thinking way off the mark?
