A stone is attached to the end of an elastic string and whirled round in a circle path of radius 80cm if the stone makes 9 complete revolution in 3 seconds .find its angular and linear velocities during this period
Answered by bobpursley
velocity=distance/time=2PI*.8/3 *9

angular velociy=2PI/peiod= 9*2PI/3
linear velociyt= w*radius

A stone is tied to a string is made to revolve in horizontal circle of radius 4m with an angular speed of 2 radian per seconds with what tangential velocity will the stone move off the circle if the string cuts
