JEE Main Physics question

A particle is moving with a uniform acceleration along a straight line . Its speed at and are 2 ms and 14 ms respectively. Then,

(A)Its speed at the mid-point of is 10 msCorrect
(B)Its speed at a point such that is 4 ms
(C)The time to go from to the mid-point of is double that to go from the mid-point to Correct
(D)None of the above

Answer: (A),(C)

Mid-point speed ms — (A) is true. At with : using and , we get , so
