Question

A body travels along a circular path of radius 70m.After travelling half a revolution in 20s, find the (i) average velocity , (ii) average speed.

Answer 1

Answer:radius=70m

Circumference=2πr

But half a revolution will be πr=22/7×70=220m

So

Time=20s

Average velocity=distance/time=220/20=11m/s

Average speed= 11m/s (same way)
