The driver of a car travelling at full speed suddenly sees a wall at a distance \(r\) directly in front of him. To avoid collision,

1. he should apply brakes sharply
2. he should turn the car sharply
3. he should apply brakes and then sharply turn
4. None of these

Correct answer: he should apply brakes sharply

Solution

Since the wall is directly in front, the immediate need is to reduce the car’s speed along its current path. Braking sharply is the correct response; turning sharply may not be possible or safe at such a short distance.
