A particle of mass m is moving along the x-axis with speed v when It collides with a particle of mass 2m initially at rest. After the collision, the first particle has come to rest and the second particle has split into two equal-mass pieces that are shown in the figure. Which of the following statements correctly describes the speeds of the two places? (θ>0)

Three blocks are placed on smooth horizontal surface and lie on same horizontal straight line. Block 1 and block 3 have mass m each and block 2 has mass M(M>>m). Block 2 and block 3 are initially stationary, while block 1 is initially moving towards block 2 with speed v as shown. Assume that all collisions are head on and perfectly elastic. What value of M/m ensures that block 1 and block 3 have the same final speed?

A ball of mass m is attached to a cord of length L, pivoted at point O, as shown in Fig. The ball is released from rest at point A, swings down and makes an inelastic collision with a block of mass 2m kept on a rough horizontal floor. The coefficient of restitution of collision is e=2/3 and coefficient of friction between block and surface is After collision, the ball comes momentarily to rest at C when cord makes an angle of θ with the vertical and block moves a distance of 3L/2 on rough horizontal floor before stopping. The values of μ and θ are, respectively,
