An airplane propeller is 2.68 m in length (from tip to tip) and has a mass of 107 kg. when the airplane's engine is first started, it applies a constant torque of 1930 nm to the propeller, which starts from rest.
a. what is the angular acceleration of the propeller? treat the propeller as a slender rod.
b. what is the propeller's angular speed after making 5.00 rev?
c. how much work is done by the engine during the first 5.00 rev?
d. what is the average power output of the engine during the first 5.00 rev?
e. what is the instantaneous power output of the motor at the instant that the propeller has turned through 5.00 rev?
