angular velocity = 300(2π) radians/minute
= 300(2π)/60 radians/sec
= 10π radians/sec
circumference = 2π(30) = 60π cm
so the linear velocity at the tip is 300(60π) cm/min
= 300(60π)/60 cm/se
= 300π cm/sec
or
3π m/sec
= 300(2π)/60 radians/sec
= 10π radians/sec
circumference = 2π(30) = 60π cm
so the linear velocity at the tip is 300(60π) cm/min
= 300(60π)/60 cm/se
= 300π cm/sec
or
3π m/sec
