**Problem**: Three students derive the following equations in which x refers to distance traveled, v the speed, a the acceleration (m/s2), t the time, and the subscript zero means a quantity at time t = 0. Which of these equations could possibly be correct according to a dimensional check?(a) x = vt2 + 2at,(b) x = v0t + 1/2at2,(c) x = v0t + 2at2.

###### Problem Details

Three students derive the following equations in which x refers to distance traveled, v the speed, a the acceleration (m/s^{2}), t the time, and the subscript zero means a quantity at time t = 0. Which of these equations could possibly be correct according to a dimensional check?

(a) x = vt^{2} + 2at,

(b) x = v_{0}t + 1/2at^{2},

(c) x = v_{0}t + 2at^{2}.
