List of top Physics Questions on Center of Mass and Linear Momentum asked in AP EAPCET

Two particles of masses 5 g and 3 g are separated by a distance of 40 cm. The centre of mass of the system of these two particles lies:
Two particles of masses 1 g and 2 g move towards each other with velocities 10 m/s and 20 m/s respectively. The velocity of the centre of mass of the system of the two particles is
Which of the following statements regarding ntre of mass is NOT true?
A particle of mass 10 g is moving towards east with a velocity of $10 \text{ ms}^{-1}$ and another particle of mass 15 g is moving towards north with a velocity of $5 \text{ ms}^{-1}$. The magnitude of the velocity of the ntre of mass of the system of the two particles is
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
