A set of n identical cubical blocks lies at rest parallel to each other along a line on a smooth horizontal surface. The separation between the near surfaces of any two adjacent blocks is L . The block at one end is given a speed v towards the next one at time t = 0 . All collisions are completely inelastic, then

Three objects A ,B and C are kept in a straight line on a smooth horizontal surface. These have masses m, 2m and 3m , respectively . The head – on elastic collision takes place between A and B and then B makes completely inelastic collision with C. All motions occur on the same straight line. The final speed of C will be

The ball A is reached and it makes head on collision with B. The masses of A and B are same 1. After collision , A comes to rest and B moves with velocity of A just before collision 2. The maximum height attained by ball B is L/2 3. The maximum angle made by string attached to B is 60^∘ 4. All options are correct
