In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.47 kg) and embeds itself in block 2 (mass 2.10 kg). The blocks end up with speeds v1 = 0.670 m/s and v2 = 1.46 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block
