Two particles were projected one by one with the same initial velocity from the same point on level ground. They follow the same prabolic trajectory and are found to be in the same horizontal level, separated by a distance of 1 m, 2 s after the second paricle was projected. Assume that the horizontal component of their velocities is 0.5 m/s.

An ideal spring is permanently connected between two blocks of masses M and m. The blocks-spring system can move over a smooth horizontal table along a straight line along the length of the spring as shown in Fig.The blocks are brought nearer to compress the spring and then released. In the subsequent motion,

Two small rings each of mass ‘m’ are connected to a block of same mass ‘m’ through inextensible light strings. Rings are constrained to move along a smooth horizontal rod. Initially system is held at rest (as shown in figure) with the strings just taut. Length of each string is ‘l’. The system is released from the position shown. Find the speed of the block (v) and speed of the rings (u) when the strings make an angle of theta = 60^(@) with vertical.
