A wheel free to rotate about its axis that is not frictionless
is initially at rest. A constant external torque of +52 N·m is
applied to the wheel for 23 s, giving the wheel an angular velocity
of +640 rev/min. The external torque is then removed, and the wheel
comes to rest 120 s later. (Include the sign in your answers.)

A standard door into a house rotates about a vertical axis
through one side, as defined by the door's hinges. A uniform
magnetic field is parallel to the ground and perpendicular to the
axis. Through what angle must the door rotate so that the magnetic
flux that passes through it decreases from its maximum value to 1/4
of its maximum value? Give your answer in degrees, not radians.

Consider a ‘physical pendulum’ made of a meter stick (length L =
1 m, mass 0.2 kg) with a hole drilled through it at the 5 cm mark.
The stick is free to rotate (in a vertical plane) around a nail
that goes through the hole and into a wall. Assume no friction
between the nail and the hole. The stick’s moment of inertia about
the nail is I=0.1 kgm2. (Use g=10 m/s2)
If the pendulum is released from rest...
