Velocity (v) and acceleration (a) in two systems of units 1 and 2 are related as v_2=n/(m^2) v_1 and a_2=(a_1)/mn respectively. Here m and n are…
Velocity $\displaystyle (v)$ and acceleration (a) in two systems of units $\displaystyle 1$ and $\displaystyle 2$ are related as $\displaystyle v_2=\frac{\mathrm{n}}{\mathrm{m}^2} v_1$ and $\displaystyle \mathrm{a}_2=\frac{\mathrm{a}_1}{\mathrm{mn}}$ respectively. Here m and n are constants. The relations for distance and time in two systems respectively are :
Official answer
(1)
$\displaystyle \frac{\mathrm{n}^3}{\mathrm{~m}^3} \mathrm{~L}_1=\mathrm{L}_2$ and $\displaystyle \frac{\mathrm{n}^2}{\mathrm{~m}} \mathrm{~T}_1=\mathrm{T}_2$
