Answer 1

Answer:

t=4sec

Explanation:

Sol: As u = 0, and a is constant

Applying \displaystyle S = u t + \frac{1}{2}a t^2

In first case ,

\displaystyle S/4 = 0 + \frac{1}{2}a 2^2 ..(i)

In second case ,

\displaystyle S = 0 + \frac{1}{2}a t^2 ..(ii)

Dividing (ii) by (i), we get

\displaystyle 4 = \frac{t^2}{4}

t = 4 sec
