Question

The driver of a truck travelling with a velocity $v$ suddenly notices a brick wall in front of him at a distance $d$. To avoid crashing into the wall

• A. he should apply brakes
• B. he should take a circular turn without applying brakes
• C. both $\left(a\right)$ and $\left(b\right)$ alternately
• D. crashing is inevitable

Answer 1

The correct option is A he should apply brakes

For taking a circular turn to avoid accident, the acceleration acquired will be $\frac{v^2}{d}$. Thus additional effort is required to meet this acceleration. Hence he should apply brakes
