A model of a helicopter rotor has four blades, each 3.00 m in length from the central shaft to the tip of the blade. The model is rotated in a wind tunnel such that it makes one complete circle in a time of 0.100 s.
A. What is the speed of the blade tip? Express your answer in meters per second.
B. What is the radial acceleration of the blade tip, expressed as a multiple of the acceleration g due to gravity? Express your answer as a multiple of the acceleration due to gravity g.
