What is the ration of the sistance travelled by constan a body falling freely from frest in the first, second , an dthird sconds of its fall.

Explanation

Hence, ` u =0, a= g` ,
Using the relation ` D_(n) =u + a/2 (2 n-1)`
we have ` D_(1) : D_(2) : D_(3) = g/2 ( 2xx 1-1)`
` : g/2 (2 xx 2 -1) : g/2 (2 xx 3-1) = 1: 3: 5`.
