Two car `A` and `B` travelling in the same direction with velocities `v_1` and `v_2(v_1 gt 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 wil be no collision when.

A

`d lt ((v_(1)-v_(2))^(2))/(2a)`

B

`d lt (v_(1)^(2)-v_(2)^(2))/(2a)`

C

`d gt ((v_(1)-v_(2))^(2))/(2a)`

D

`d gt (v_(1)^(2)-v_(2)^(2))/(2a)`

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 2m//s^(2) . There will be no collision when :-

Two cars, A and B, are traveling in the same direction with velocities v_(a) and v_(b) respectively. When car is at a distance d behind car B, the brakes on A are applied, causing a deceleration at a rate a. Show that to prevent a collision between A and B it is necessary that:

Two cars 1 and 2 move with velocities v_(1) and v_(2) , respectively, on a straight road in same direction When the crs are separated by a destance 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) lt v_(2) , find the minimum initial separation between the cars to avoid collision between then.

Two cars 1 & 2 starting from rest are moving with speeds V_(1) and V_(2) m//s (V_(1)gtV_(2)) . Car 2 is ahead of car 1 by a meter when the driver of the car 1 sees car 2 what minimum retardation should be given to car 1 to avoid collision.

When the driver of a fast moving car suddenly applies brakes, the passengers in the car

The driver of a train moving at a speed v_(1) sights another train at a disane d , ahead of him moving in the same direction with a shower speed v_(2) . He applies the brakes and gives a constant teradation a to his train. Show that here will be no collision if d gt (v_(1) -v_(2))^(2) //2 a .

A car is moving with speed u. Driver of the car sees red traffic light. His reaction time is t, then find out the distance travelled by the car after the instant when the driver decided to apply brakes. Assume uniform retardation 'a' after applying brakes.
