Homework Statement
The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.63 m and 0.99 m, respectively. The respective rotational speeds are 459 rev/min and 4132 rev/min. Calculate the speeds of the tips of both rotors.
Homework Equations
V=Rω
The Attempt at a Solution
V=(3.815m)(7.65 rev/s)
V=29.18 m/s
V=(.495m)(68.89 rev/s)
V=34.10 m/s
