A turntable of radius 8cm is rotating at 33 revolutions per second .Determine the linear speed of a point on the circumference of the turntable.
(KCSE 2009 paper 1 question 14.).

Answer Text:
#T = (2 pi)/omega rightarrow 1/33 = (2 pi)/omega rightarrow omega =2 times 22/7 times 33 =207.4#
#V =r omega = 0.08 times 207.4# = 16.59 m/s.
