A car moving with a speed of `40 km//h` can be stopped by applying the brakes after at least 2 m. If the same car is moving with a speed of `80 km//h`, what is the minimum stopping distance?

8 m

2 m

4 m

6 m

Text Solution

Verified by Experts

The correct Answer is:

(a) Speed is doubled. Therefore kinetic energy will become four times. Hence, minimum stopping distance will also become four times.
