Dimensional Analysis: The kinetic energy K of an object of mass m moving with speed v is given by the formula K = 
mv2. The SI unit of kinetic energy is the joule, J. Use this formula to express the joule in terms of the fundamental SI quantities of mass, length, and time.
A. J = kg ? m/s
B. J = kg ? m/s2
C. J = kg2 ? m2/s2
D. J = kg ? m2/s2
