A model of a helicopter rotor has four blades, each of length 3.90m from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 480rev/min .
A.) What is the linear speed of the blade tip?
given
R= 3.9
T = 480
would it just be V= 2*pi*R/t
and got = .05105
someone helped me(not at this forum) and the answer is wrong. can someone help? isn't it just asking for the velocity?
