Question

A body starts from rest and accelerates uniformly. Ratio of distances travelled in one,two and three seconds are?​

Answer 1

Using s=ut+1/2at²

put U=0 we have

distance at time t=1, s=a/2

distance at time t=2,s=2a

distance at time t=3,s=9a/2.

Answer 2

Answer:

Using s=ut+1/2at²

put U=0 we have

distance at time t=1, s=a/2

distance at time t=2,s=2a

distance at time t=3,s=9a/2.

 hence the answer is  1:4:9
