Two cars A and B Are moving in same direction with velocities 30 m/s and 20 m/s.When car A is at a distance d behined tha car B , the driver of tha car A applies brakes producing uniform retardation of 2 m/s2. Find d

Q. Two cars $A$ and $B$ are moving in same direction with velocities $30m/s$ and $20m/s$. When car $A$ is at a distance $d$ behind the car $B$, the driver of the car $A$ applies brakes producing uniform retardation of $2m/s^2$. There will be no collision when

Q. Two cars $A$ and $B$ are travelling in the same direction with velocities $v_A$ and $v_B(v_A>v_B)$. When the car $A$ is at a distance $d$ behind the car $B$ the driver of the car $A$ applies brakes producing a uniform retardation $a$. There will be no collision when

Q. Two cars A and B are travelling in the same direction with velocities $v_1$ and $v_2(v_1>v_2)$ When the car A is at a distance d ahead of the car B, the driver of the car A applied the brake producing a uniform retardation a. There will be no collision when

Q. Two cars $A$ and $B$ are travelling in the same direction with velocities $v_1$ and $v_2(v_1>v_2)$ respectively. When the car $B$ is at a distance $d$ ahead of the car $A$, the driver of the car $A$ applied the brake producing a uniform retardation $a$. There will be no collision if

Q. Two cars 1 and 2 move with velocities $v_1$ and $v_2$ respectively, on a straight road in same direction. When the cars are separated by a distance d, the driver of car 1 applies brakes and the car moves with uniform retardation $a_1$. Simultaneously, car 2 starts accelerating with $a_2$. If $v_1{>v}_2$. Find the minimum initial separation between the cars to avoid collision between them.
