Helicopter blades withstand tremendous stresses. In addition to supporting the weight of the helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. The tip of a 4.00 m long helicopter blade that rotates at 5 Hz. (a) What is the linear speed of the tip of the blade? (b) What is the centripetal acceleration at the tip? (c) How many g’s is this?
