Question

2) An athlete runs a race in a semi circular track from A to B. O is the midpoint of AB
as shown in the figure What is the distance and displacement of the athlete.​

Answer 1

Answer:

distance = 10π = 31.4 m

displacement 20 m

Explanation:

we know that distance is half the circumference of circle

so distance= πr = 10*3.14 = 31.4 m

displacement is shortest distance which is 10+10 = 20m
