here is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

An airplane propeller is 2.08 m in length (from tip to tip) and

has a mass of 117 kg. When the airplane's engine is first started,

it applies a constant torque of 1950 N*m to the propeller, which starts from rest.

-What is the angular acceleration of the propeller? Treat the propeller as a slender rod.

For this part i got 46.23 rad/s^2 finding first I=(1/12)ML^2

and then plugging that into acc angular = torque/I

What is the propeller's angular speed after making 5.00 rev?

-for this part i get confused, am i supposed to use

5 rev "per min". i used the formula v = w*r where

w= 2*pi*frequency, but it is not right.

can anyone direct me to the right formula??

thanks.
