Question

An airplane propeller is 3.08 in length (from tip to tip) and has a mass of 152 . When the airplane's engine is first started, it applies a constant torque of 1900 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 ?



Part C
How much work is done by the engine during the first 5.00 ?


Part D
What is the average power output of the engine during the first 5.00 ?


Part E
What is the instantaneous power output of the motor at the instant that the propeller has turned through 5.00

Explanation / Answer

find moment of inertia. Then uses torque formula to find asnwer
