1.	In a along distance race, the athletes were expected to take four rounds of the track such that the line of finish was same as the line of start . Suppose the length of the track was `200 m`. (a) What is the total distance to be covered by the athletes ? (b) What is the displacement of the athletes when they touch the finish line? ( c ) Is the motion of the athletes uniform or non -uniform? (d) Is the displacement of an athlete and the distance moved by him at the end of the race equal?
Answer» Correct Answer - (a) `800 m` , (b) zero ,( c ) non - uniform , (d) No (a) Distance covered ` = 4 xx 200 = 800 m`. (b) Displacement `= 0 , as athletes finish at the starting line. ( c ) Motion is non - uniform as the direction is changing . (d), No, displacement and distance covered are not equal.
