Question

Kindly solve this using proper explanation..​

Answer 1

Answer:

Option C) 3

Explanation:

Using s=ut +1/2at^2

s1=1/2at^2 because u=0 initially

s1=1/2(a)(4)=2a

s2=s3-s1 where S2 is distance moved in 4 seconds

s2=1/2a(4)^2-2a=8a-2a=6a

Therefore s2/s1=6/2=3

Here I have used s instead of theta and a instead of alpha
