(6) Beginning with the initial substitution into the definition of kinetic energy, verify that the units obtained are units of energy.
In the first substitution, the square root and the exponent of two cancel each other. Since all that is of concern is the units of the problem, the dimensionless fraction of 1/2 can be ignored. The units of equation (2) are therefore
Atmospheres and liters can then be converted to SI units.
