ll block (block 1) of mass m, attached to an ideal string of length L, is initially held so that the string is taut and horizontal at height Labove a frictionless table, as shown in Fig.2. A second small block (block 2) of mass 3mis placed on the table right under the point of attachment of the string holding block 1. The tabletop is at height 2L above the floor. Block 1 is then released from rest and collides elastically with block 2 at time t=0. The acceleration due to gravity has magnitude g and air resistance is negligible. a)Determine the time t2at which block 2 hits the floor.
