A blade on a water turbine turns 240º in 1.25 s. Find the linear speed of a point on the tip of the blade 0.710 m from the axis of rotation.
Round the answer to two decimal places.
-----
240º = 2/3 of a revolution = 4pi/3 radians
Angular speed = (4pi/3)/1.25 = 16pi/15 rad/sec
Linear speed = (16pi/15)*0.71 m/sec
----
You didn't spec units, m/sec, cm/sec, furlongs/week, etc.
Convert if you want.
