An airplane propeller is 2.28 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 net torque of 1990 N⋅m 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 ?
