Question

A particle revolving in a circular path completes first one third of circumference in 2 sec, while next one third in 1 sec. The average angular velocity of particle will be – ("in "rad//sec)

Answer 1

`theta_(1)=(2pi)/(3)and theta_(2)=(2pi)/(3)"total time T"=2+1=3s therefore ltomega_(av)gt(theta_(1)+theta_(2))/(T)=((2pi)/(3)+(2pi)/(3))/(3)=((4pi)/(3))/(3)=(4pi)/(9)"rad/s"`
