Question

(ntse exam question) A body falling from rest describes distances S1, S2 and S3 is the first, second and third seconds of
its fall. Then the ratio of S1 : S2 : S3 is :
(1) 1 : 1 : 1 (2) 1 : 3 : 5
(3) 1 : 2 : 3 (4) 1 : 4 : 9

Answer 1

Then the ratio of S1 : S2 : S3 is : (2) 1 : 3 : 5

The distance travelled are 5m, 15m and 25m.
(Taking g=10 m/s²)
