Question:(adsbygoogle = window.adsbygoogle || []).push({});

"An airplane engine delivers 1.5x10^6 W at an angular velocity of 2400 rev/min."

A) Compute torque developed

B) If a drum of negligible mass, .5m in diameter, were attached to the motor shaft, and the power output of the engine were used to raise a weight hanging from a rope wrapped around the drum, how large a weight could be lifted?

C) With what velocity would it rise?

WORK DONE: (Almost nothing, kinda looking for where to start with this question)

I know since they gave us the rev/min that the angular velocity is (2400*2PIE)/60

Other then this.. I have no clue how to start this problem.

Solved: Thank you for your help Astronuc, you saved me hours of finding that.
