Question

Speeds of two identical cars are u and 4u, respectively, at a specific instant. If the same retardation is applied to both the cars, the ratio of the respective distances in which the two cars are stopped, from that instant, is

Correct answer: (D) 1 : 16. Both the cars are given the same deceleration simultaneously and both finally stop. Formula relevant to motion : u^2=2as ∴ For the first car, s⁡_1 = u^2 2 a For the second car, s⁡_2 = (4 u⁡^2)/(2 a) = (1 6 u⁡^2)/(2 a) ∴ (s⁡_1)/(s⁡_2) = 1/(1 6)

Speeds of two identical cars are $u$ and $4 u$ , respectively, at a specific instant. If the same retardation is applied to both the cars, the ratio of the respective distances in which the two cars are stopped, from that instant, is
