Two blocks of maases $10\,kg$ and $4\,kg$ are connected by a spring of negligible mass and placed on a frictionless horizontal surface. An impulse gives a velocity of $14\,m/s$ to the heavier block in the direction of the lighter block. The velocity of the centre of mass is ......... $m/s$
The velocity of the centre of mass of a rigid rod with respect to an observer $O$ is $\vec v = \left( {2\hat i + 3\hat j} \right) ms^{-1}$ . The rod has an angular velocity about its centre of mass given by $\vec \omega$  =$\left( {3\hat j + 4\hat k} \right) s^{-1}$ . Let A be a point on the rod with position vector $2\left( {\hat i + \hat k} \right) m$ with respect to the centre of mass. The velocity of the point $A$ with respect to $O$ is
