149846 The motor of an engine is rotating about its axis with an angular velocity of \(100 \mathrm{rev} / \mathrm{m}\). It comes to rest in, \(15 \mathrm{~s}\), after being switched off. Assuming constant angular deceleration. What are the numbers of revolutions made by it before coming to rest?

149847 A flywheel rotates about an axis. Due to friction at the axis, it experiences an angular retardation proportional to its angular velocity. If its angular velocity falls to half while it makes \(\mathrm{n}\) rotations, how many more rotations will it make before coming to rest?

149848 A circular disc rotating with frequency \(f_{0}=\mathbf{1 . 3}\) rev/sec comes to a stop in 30 seconds. The approximate angular acceleration is:

149849 A wheel has angular acceleration of \(3.0 \mathrm{rad} / \mathrm{s}^{2}\) and an initial angular speed of \(2.00 \mathrm{rad} / \mathrm{s}\). In a time of \(2 \mathrm{~s}\) it has rotated through an angle (in radian) of
