An airplane propeller is 2.68 m in length (from tip to tip) and
has a mass of 112 kg . When the airplane’s engine is first started,
it applies a constant torque of 1890 N⋅m to the propeller, which
starts from rest.

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 ?
