149787 A wheel undergoes a constant angular acceleration from time \(t=0\) to \(t=20\) s and thereafter angular acceleration is zero. If angular velocity at \(t=2 \mathrm{~s}\) is found to be \(5 \mathrm{rad} / \mathrm{s}\), then the number of revolutions made by the wheel in time interval \(\mathbf{t}=0 \mathrm{~s}\) to \(\mathbf{t}=\mathbf{5 0} \mathrm{s}\) is:
