Kinetic energy is defined as ½ mv2, where m is the mass of the object, and v is the velocity (or speed). Velocity can be measured in miles per hour, or in meters per second (for example). Enter the letter of the following possibilities that could NOT be considered a unit of energy.
a. Kg (meter^2/sec^2)
b. Inch (meter-gram/second-year)
c. gram (cm^2/second^2)
d. kg (mile/hour^2)
e g (nanometer^3/week-hour-foot)
