Speeds of two identical cars are u and 4 u at the specific instant. The ratio of the respective distances in which the two cars are stopped from that instant is

Options

  1. A1 : 1
  2. B1 : 4
  3. C1 : 8
  4. D1 : 16

Correct answer

D. 1 : 16

Step-by-step solution

Use u^2=2 as. a is same for both cases s ₁= u ^2 / 2 a ; s ₂=16 u ^2 / 2 a =16 ~s ₁ s ₁: s ₂=1: 16
