Question
A helicopter blade spins at exactly 100 revolutions per minute. Its tip is 5.00 m from the center of rotation. (a) Calculate the average speed of the blade tip in the helicopter's frame of reference. (b) What is its average velocity over one revolution?
1. $52\textrm{ m/s}$
2. The blade tip has zero displacement since it returns to its starting position after one revolution. It therefore has zero average velocity.
