The turbine and associated rotating parts of a jet engine have a total moment of inertia of 23 kg m2. The turbine is accelerated uniformly from rest to an angular speed of 140 rad/s in a time of 27 s.

(a) Find the angular acceleration.

(b) Find the net torque required.

(c) Find the angle turned through in 27 s.

(d) Find the work done by the net torque.
