Position of two vehicles $\mathrm{A}$ and $\mathrm{B}$ with reference to origin $\mathrm{O}$ and their velocities are as shown. Then, if they move with the same velocities shown (a) they will collide in $8 \mathrm{~s}$. (b) distance of closest approach is $100 \mathrm{~m}$. (c) their relative velocity is $\frac{40}{\sqrt{3}} \mathrm{~m} \mathrm{~s}^{-1}($ modulus value $)$. (d) they reach the closest position in $7.5 \mathrm{~s}$.

Car A is traveling at 40 km ∕hr and applies the brakes at the position shown so as to arrive at the intersection C at a complete stop with a constant deceleration. Car B has a speed of 65 km ∕hr at the instant represented and is capable of a maximum deceleration of 5 m ∕sec2. If the driver of car B is distracted and does not apply his brakes until 1.30 seconds after car A begins to brake, the result being a collision with car A, with what relative speed will car B strike car A? Treat both cars as particles.
