Two wooden blocks of mass \(M_1\) and \(M_2\) rest on a frictionless table. A bullet of mass \(m\) is fired at \(M_1\) with speed \(v\), which embeds in it, and the two together finally collide with \(M_2\). Find the velocity of \(M_2\) after collision.
[Ignore any energy loss and treat the problem to be one dimensional]

Ball \(A\) of mass \(1\,\text{kg}\) moving along a straight line with a velocity of \(4\,\text{m s}^{-1}\) hits another ball \(B\) of mass \(3\,\text{kg}\) which is at rest. After collision, they stick together and move with the same velocity along the same straight line. If the time of impact of the collision is \(0.1\,\text{s}\), then the force exerted on \(B\) is
