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 `S` meter when the driver of the car 1 sees car 2. What minimum retardation should be given to car 1 to avoid collision.

A

`(v_(1) - v_(2))/(s)`

B

`(v_(1) + v_(2))/(s)`

C

`((v_(1) + v_(2))^(2))/(2s)`

D

`(v_(1) - v_(2))^(2))/(2s)`

Text Solution

Verified by Experts

The correct Answer is:
D
`u_("rel") = v_(1) - v_(2), v_("rel") = 0, v_("rel")^(2) = u_("rel")^(2) = 2as`
