An airplane propeller is 2.78{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 1970{N * m} to the propeller, which starts from rest.
Part A What is the angular acceleration of the propeller? Treat the propeller as a slender rod.
Part B What is the propeller's angular speed after making 5.00{rev}?
Part C How much work is done by the engine during the first 5.00{rev}?
Part D What is the average power output of the engine during the first 5.00{rev}?
Part E What is the instantaneous power output of the motor at the instant that the propeller has turned through 5.00{rev}?
