Question

17. The position x of a body moving with uniform
acceleration depends on time t as x = 2t + 612
The numbers 2 and 6 in the equations are
(1) Dimensionless variable
(2) Dimensional constant
(3) Dimensionless constant
(4) Dimensional variable​

Answer 1

Answer:

(2) Dimensional constant

Explanation:

We have three formulae

x = u + at

x = ut + 0.5at×t

v×v - u×u = 2ax

Where

x = distance meter (m)

u = initial velocity

meter per second (m/s)

v = final velocity

meter per second (m/s)

t = time seconds (s)

a = acceleration

meter per second square (m/s^2)

All of these quantities have dimensions
