(i) What is the total distance to be covered by the athletes?
(ii) What is the displacement of the athletes when they touch the finish line?
(iii) Is the motion of the athletes uniform or non-uniform?
(iv) Is the displacement of an athletes and distance moved by him at the end of race equal?

Answer 1

i)total distance = 800m ii) displacement =0m iii) motion of athlete is non uniform iv) no the distance travelled is 800m while displacement on zero at the initial point and final point are same.
