Chetan's father wanted to buy a car. He visited many showrooms to find out the price and the specifications of various cars. In one of the showrooms,he was told by the salesman that their car had excellent brakes such that the car stops instantaneously. Chetan's father was impressed and decided to buy that car. In the evening,he discussed this with his family. Chetan told his father that such a car cannot be made and the salesman had lied to him. He told his father that he should not buy that car and,moreover,never from that showroom. He explained to his father why it is not possible. His father was convinced and promised to visit another showroom and be careful this time.
$(a)$ What might have been the explanation given by Chetan to convince his father?
$(b)$ What values do you see in Chetan?
$(a)$ What might have been the explanation given by Chetan to convince his father?
$(b)$ What values do you see in Chetan?
(N/A) The salesman's claim is scientifically impossible. If a car stops instantaneously,the time taken $(t)$ for the change in velocity is $0$. Since retardation (deceleration) is defined as $a = \frac{v - u}{t}$,if $t = 0$,the retardation becomes infinite. An infinite force would be required to produce infinite retardation,which is physically impossible.
$(b)$ Chetan demonstrates critical thinking,scientific awareness,honesty,and a sense of responsibility toward his family's well-being.
