Question

Find Distance and displacement​

Answer 1

Answer:

distance-628m

displacement-0m/s

Explanation:

diameter of the circular track = 200m

time taken =40s

As the track is circular, the distant will be equal to the circumference of the track

circumference= πd

= 3.14*200

= 628m

As the athlete runs back to the position from where he started,

the displacement=0m/s

Answer 2

Given,

Diameter = 200m

Time = 40 sec

Distance = 200m/40sec

= 5 m/sec

2min 20 sec in sec

120+20=140 sec

200 m / 140 sec = 1.42 m/sec

Displacement = It will be 0 because the track is cicular and there is no short way.
