🤓 Based on our data, we think this question is relevant for Professor Sen's class at UB.

Solution: 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

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.
