         Shikhaj and Sharman went to Mathura through Yamuna-Expressway. Shikhaj started the car and accelerated so highly that the car was running at 108 km/h within 10 seconds. Sharman stopped him from doing so and told him that over speeding on road was a straight invitation to life staking situation. Though shikhaj wanted the adventure of speeding, but he was convinced by Sharman. (i) Why do you think it is dangerous to drive fast on road? (ii) Which values of Sharman are worth appreciating? (iii) What is the acceleration of the car?

Answer:

                          (i) Accidents occuring with fast moving vehicles are dangerous and might be fatal. (ii) Sharman is caring, concerned, responsible and convincing. (iii) \[a=\frac{\upsilon -u}{t}=\frac{30-0}{10}=3\text{m/s}\] \[[\because \upsilon =108\,km/h=108\times \frac{5}{18}=6\,\text{m/s}]\]
