Question

In a long distance race the athletes were expected to take four rounds of track such that the line of finish was the same as the start.
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 athlete uniform or non uniform?
d)Is the distance and the Displacement at the end of the race equal?

Answer 1

1.it is four times the circumference of the track
2.displacement of athelete=0(initial posn. same as that of the final)
3.motion is non-uniform as direction keeps changing
4.no the distance and displacement are not same.

Answer 2

a). The total distance to be covered by the athletes are four times the length of track.

b). Displacement of the athletes are Zero (0) when they touch the finish line because initial and final points are same.

c). The motion of the athletes are non uniform as the direction is keep changing at every point.

d). The distance and the displacement at the end of the race are not equal.
