A body is freely dropped from a height h above the ground. Find the ratio of distances fallen in first one second, first two seconds, first three second ,also find the ratio of distances fallen in `1^(st)` second, in `2^(nd)` second, in `3^(rd)` seconds

Explanation

Distance covered by the car during the application of brakes by driver
`s_(1)=ut=(54xx5/18)(0.2)=15xx0.2=3.0 m`
After applying the brakes, `v=0, " "u=15 m//s, a=6 m//s^(2) s_(2)=?`
Using `v^(2)=u^(2)-2as rArr 0=(15)^(2)-2xx6xxs_(2)rArr 12 s_(2)=225rArr s_(2)=225/12=18.75 m`
Distance travelled by the car after driver sees the need for it `s=s_(1)+s_(2)=3+18.75-21.75 m`
