A student uses dimensional analysis to check the equation v = a*t, where v is velocity, a is acceleration, and t is time. Which statement correctly describes the result?

The equation is dimensionally consistent because m/s^2 times s gives m/s The equation is inconsistent because acceleration cannot multiply time The equation is inconsistent because the result has units of m/s^2 The equation is consistent only if time is measured in hours

Correct Answer:

The equation is dimensionally consistent because m/s^2 times s gives m/s
