A particle of mass \(15 \mathrm{~kg}\) is moving with a uniform speed \(8 \mathrm{~ms}^{-1}\) in \(\mathrm{xy}\)-plane along the line \(3 y=4 x+10\), then the magnitude of its angular momentum about the origin in
\(\mathbf{k g}-\mathbf{m}^{2} \mathrm{~s}^{-1}\) is... \(\ left(\sin 53^{\circ}=\frac{4}{5}\ right\)
149978 A solid sphere of mass \(2 \mathrm{~kg}\) and radius \(1 \mathrm{~m}\) is free to rotate about an axis passing through its centre. A constant tangential force ' \(F\) ' is required to rotate the sphere with \(10 \mathrm{rad} \mathrm{s}^{-1}\) in 2 s starting from rest. Then the value of \(F\) is
149979 Two discs of same moment of inertia rotating about their regular axis passing through centre and perpendicular to the plane of disc with angular velocities \(\omega_{1}\) and \(\omega_{2}\). They are brought into contact face to face coinciding the axis of rotation. The expression for loss of energy during this process is
