Correct answer: (B) 10 m. v_AB=10 m s^(-1), a_AB=-5 m s^(-2) s_AB=10t-5/2t^2 Minimum displacement of A w.r.t. B s_ABmin is at t=10/5=2 Minimum separation =20-10=10 m

Two cars $A$ and $B$ are moving with a speed of $15$ $m s^{- 1}$ and $5$ $m s^{- 1}$ and acceleration of the cars are $1$ $m s^{- 2}$ and $6 m s^{- 2}$ respectively. Then the minimum separation between them is
