A small 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 L above a frictionless table, as shown in Fig.2. A second small block (block 2) of mass 3m is 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. point of attachment block 1 block 2 Зт 2L Figure 2 a- Determine the time t2 at which block 2 hits the floor.

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
