Question

Two cars C1 and C2 moving in the same direction on a straight road with velocity 12 metre per second and 10 metre per second respectively when the separation between the two cars was 200 metre C2 start accelerating to avoid collision what is the minimum acceleration of C2 so that they don't collide

Answer 1

Answer:

As the two cars are having velocities 12m/s and 10m/s respectively hence the relative velocity of the car c1 with respect to c2 will be 12-10=2m/s. thus, the car will appear to move with 2m/s for car c2.

As, the separation between the cars is 200m hence we can use the equation collision which we will get.  

The minimum acceleration to avoid collision will be a m/s^2.

v^2 = u^2 - 2aS.

0=2^2 - 2*a*200.

a = 0.01 m/s^2.
