A car travelling at a speed of 30 km/hour is brought to a halt in 8 m by applying brakes. If the same car is travelling at 60 km/hour, it can be brought to a halt with the same braking force in

A

8 m

B

16 m

C

24 m

D

32 m

Text Solution

Verified by Experts

The correct Answer is:

D

`s prop u^(2)` i.e. if speed becomes double then stopping distance will become four times i.e. `8xx4 = 32m`
