u=0, a=g=9.8m/s^2S(distance in last second)=u+0.5a(2n-1)100=0+0.5×9.8(2n-1)Therefore, n=10.7
That means,total time travel stone took to reach ground=10.7 s
Now, height=ut + 0.5at^2h=0×t + 0.5 × 9.8 ×(10.7)^2h=561 m
That means,total time travel stone took to reach ground=10.7 s
Now, height=ut + 0.5at^2h=0×t + 0.5 × 9.8 ×(10.7)^2h=561 m
