Answer 2

First find the total height covered by the stone in 5seconds.

Which can be calculated as

h=Vit+0.5gt2

since stone is dropped its initial velocity will be 0

therefore

h=0.5gt2

since t=5

H=122.5m is the total height covered by the stone in 5sec.

Now find the distance covered in 3sec by using procedure:

h=0.5(9.8)(3)2=44.1m is the distance covered in 3sec.

now subtract Distance From Height you will get remaining distance which is to be covered

122.5-44.1=78.4m(now we want the time for this remaining distance)

Since h=0.5gt2

T=(2h/g)1/2

T={2(78.4)/9.8}0.5=4sec

Hope You Will Understand.
