Question

Solution

Correct option is

1 : 9

Since the initial velocity of the stone is zero, the total time taken by the stone to hit the ground is given by   = 5 s

During the first second, the stone falls a distance h1 given by  During the first four seconds, the stone falls a distance h given by   Distance h2 through which the stone falls in the last (i.e. fifth) second

= 125 – 80

= 45 m. .
