150170 A disc of moment of inertia \(2 \mathrm{~kg}-\mathrm{m}^{2}\) revolving with \(8 \mathrm{rad} / \mathrm{s}\) is placed on another side of moment of inertia \(4 \mathrm{~kg}-\mathrm{m}^{2}\) revolving \(4 \mathrm{rad} / \mathrm{s}\). What is the angular frequency of composite disc?

150171 Two blocks of masses \(10 \mathrm{~kg}\) and \(4 \mathrm{~kg}\) are connected by a spring of negligible mass and placed on a horizontal frictionless surface. An impulse gives a velocity of \(14 \mathrm{~m} / \mathrm{s}\) to the heavier block in the direction of the lighter block. What is the velocity of the centre of mass?
