Helicopter blades withstand tremendous stresses. In addition to supporting the weight of a helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. A. Calculate the magnitude (in m/s2) of the centripetal acceleration at the tip of a 3.40 m long helicopter blade that rotates at 240 rev/min. B. Compare the linear speed of the tip with the speed of sound (taken to be 340 m/s). Vtip/VSound =
