Question

plz solve this____the answer is options 2

Answer 1

5th half second means distance traveled from 2 seconds to 2.5 seconds

So find distance traveled in 2.5 seconds using S=ut + 1/2a t^2 which is 6.25m

and distance traveled in 2 seconds is 4m

Clearly 6.25-4 = 2.25m which is the distance traveled in the 5th half second.
