Here is a quantity I have made up. Determine the units it should have. The variables m, v, a, and r are what we have been using in this unit.

The variable p is the density. \frac{m^{2} v^{2} a}{r^{2} \rho} \frac{m^{6}}{s^{4}} \bigcirc N \frac{m^{2}}{s^{2}} \bigcirc N \frac{m^{5}}{s^{2}} \text { N }^{2} m^{3}
