motion in one dimension

  • An automobile is traveling at 50 kmh−1, can be stopped at a distance of 40 m by applying brakes. If the same automobile is traveling at 90 kmh−1, all other conditions remaining same and assuming no skidding, the minimum stopping distance in metre?
    Here I have to find s =?
    I know v = 50 km/h and s = 50 m for automobile A and v = 90 m/h and s = ? and I know the formula v^2 - u^2 = 2as
    But how to apply here to find stopping distance?
