An athlete completes one round of a circular track of diameter 200m in 40s .what will be the distance covered and the displacement at the end 2 min 20s ?
An athlete completes one round of a circular track of diameter 200m in 40s .What will be the distance covered and the displacement at the end 2 min 20s?
Since,
The
athelete complets one round in 40seconds
Therefore,
No. of revolution in 2min
20seconds=(2*60+20)/40 =140/40=
3.5
The 3.5 revolution means 3 complete
revolution and a half revolution
Therefore,
The athelete is on the diametrically
opposite side of the starting point.
Therefore,
The
displacement = the length of diameter
⇒200m
Thank You ………….
