A stone falls from a balloon that is descending at a uniform rate of $12\,\,m/s$. The displacement of the stone from the point of release after $10 \,sec$ is.......$m$
($g = 9.8\,m/{s^2}$)
$u = 12\;m/s$, $g = 9.8\;m/{\sec ^2}$, $t = 10\;\sec $
Displacement $ = ut + \frac{1}{2}g{t^2}$
$ = 12 \times 10 + \frac{1}{2} \times 9.8 \times 100 = 610\,m$
