A pulley with a radius of 8 inches rotates three times every five seconds. Find the
angular velocity of the pulley in radians/sec (round to the nearest hundredth). Find the
linear velocity to the nearst ft/hr.

  • math -

    angular speed=3rev/5sec*2pirad/rev=6PI/3
    =2PI/sec

    linear velocity? Surely you mean tangential velocity, tangential velocity=angularvelcity*radius
