Question

A stone is attached to the end of an inelastic string and whirled in a circular path of radius 30cm if the stone makes nine complete oscillation in 3seconds find the angular velocity and linear velocity during the period

Answer 1

angular velocity is ω = 2πf = 2π/(3/9) = 6π
linear velocity v = rω = 6π * 30 = 180π cm/s
