A car travelling at 80 kmph can be stopped at a distance of 60 m by applying brakes. If the same car travels at 160 kmph and the same braking force is applied. the stopping distance is

Options

  1. A240m
  2. B170m
  3. C360m
  4. D480m

Correct answer

A. 240m

Step-by-step solution

Stopping distance, S= u^2 2 a s u^2 aligned & S ₂ ~S ₁ = ( u ₂ u ₁ )^2= ( 160 80 )^2=4 & ~S ₂=4 ~S ₁=4 60=240 ~m aligned
