QA3- RELATIVE MOTION A helicopter is flying North-West at 80 m/s relative to the ground and the wind velocity is 15 m/s from the East. The helicopter's main rotor lies in a horizontal plane, has a radius of 6 m, and is rotating at 20 rad/s in a clockwise sense looking down on it. a) Calculate the helicopter's air speed and apparent heading through the air (i.e. both relative to the air). b) Calculate the maximum and minimum velocities of the blade-tips relative to the air. Hint: In hoth
