The driver of a car suddenly sees a broad wall in front of him. What he should do?

(a) Brake sharply

(b) Turn sharply

(c) Keep going

(d) Jump out of the car

This question was posed to me in examination.

I would like to ask this question from Forces in chapter Laws of Motion of Engineering Physics I

Best answer
Right choice is (a) Brake sharply

For explanation I would say: Suppose FB is the force required in applying brakes to stop the truck in distance d, then

FB × d = 1/2mv^2

Suppose FT is the force required in taking a turn of radius d then,

FT = 2FB

Clearly, it is better to apply brakes than to take a circular turn.
