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 .(adsbygoogle = window.adsbygoogle || []).push({});

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? isnt it just asking for the velocity?
