SOLVED: 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. Calculate the magnitude (in m/s^2) of the centripetal acceleration at the tip of a 30 m long helicopter blade that rotates at 200 rev/min.
