Question

47. Which of the following quantities has the
dimension as a distance?
A. vt
B. at
D. v²/a
C. 2at

Answer 1

Answer:

A   C

Explanation:

vt  =   m/s * s = m     yes

at = m/s^2 * s = ms   no....this is velocity

v^2 / a  =  m^2 / s^2  /  (m/s^2) = m   yes

2 at =   2  m/s^2 * s = 2  m/s .... no this is velocity
