2. three students derive the following equations in which v refers to the speed(m/s), a, the
acceleration (m/s), t the time, and the subscript zero (0) means a quantity at time t = 0.
here are their equations: (a) v = v. + 2at, (b) v = v, + 1/2 ata and (c) v= vo + at. which on
these could possibly be correct according to a dimensional check, and why?
