Option D

Solution

A body has a uniform motion, if if thavels equal distances in equal intervals of time. no mattor how small these time intervals mav be example, a car running at constant speed of say, $10$ metres per second, will cover equal distances of $10$ metres, every second, so its motion will be uniform. The distance$-$time graph for uniform motion is a straight line.

medium

The average time taken by a normal person to react to an emergency is one$-$fifteenth of a second and is called the 'reaction time'. If a bus is moving with a velocity of $60\, km h^{-1}$ and its driver sees a child running across the road, how much distance would. the bus had moved before he could press the brakes ? The reaction time of the people increases when they are intoxicated. How much distance had the bus moved if the reaction time of the driver were $\frac{1}{2}\, s$ under the influence of alcohol ?
