A model of a helicopter rotor has four blades, each of length 3.1 m from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 520 rev/min. Part A What is the linear speed of the blade tip? Express your answer in meters per second. Part B What is the radial acceleration of the blade tip expressed as a multiple of the acceleration of gravity, g? Express your answer as...

The blades of a helicopter rotor are 3.4m long from the central shaft to the tip of each blade. During a performance test, the rotational speed of the rotor is 530 revolutions/minute. What is the tangential speed of the rotor? What is the centripetal acceleration of the blade tip expressed in g? 1 g is 9.8m/s^2
