Guys, does anyone know the answer?

get two cars moving in the direction are 150m apart. car a being ahead of car b, at this instant velocity of car a is 3 m/s and constant acceleration of 1.2 m/s2. while the velocity of car b is 30 m/s and its uniform retardation is 0.6 m/s2. how many times do the cars cross each other? find when and where they cross with respect to given position of car a. from screen.

## 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 behind the car B , the driver of the car A applies brakes producing uniform retardation of 2 m/s^2 . There will be no collision when

Solution Verified by Toppr

Correct option is A)

Distance required to catch the speed of car B with given retardation can be found using

v 2 =u 2 +2as ⇒20 2 =30 2 +2(−2)s ⇒4s=30 2 −20 2 ⇒s=125

So the distance sholud be greater than 125 m

⇒d>125m

Therefore, A is correct option
