A particle moving with a uniform acceleration travels $24 \,m$ and $64\, m$ in the first two consecutive intervals of $4 \,sec$ each. Its initial velocity is............$m/sec$
Distance travelled in $4 \,sec$
$24 = 4u + \frac{1}{2}a \times 16$…(i)
Distance travelled in total $8$ sec
$88 = 8u + \frac{1}{2}a \times 64$…(ii)
After solving $(i)$ and $(ii)$, we get
$u = 1$m/s.
