Question

car moves a circular round about of radius 210m. calculate the displacement of car when it completes (a) half ration (b)full rotation

Answer 1

Explanation:

during half rotation distance covered is half circle i.e semicircle=pi.r

therefore distance is pi . 210 m

ii) during full rotation distance covered will be full sir i.e 2 pi.r

therefore distance covered is 2 pi.210 m = 420pi m
