1. A model of a helicopter rotor has four blades, each 2.50 m in length from the central shaft to the blade tip and is rotated in a wind tunnel at 1800 rev/min,
a. what is the linear speed of the blade tip in m/s?

b. what is the radial acceleration of blade tip?

a. R*w
b. R*w^2

where R = 2.50 m, and
w = 188.5 radians/sec (from the rev/min number)
