Problem 4: Two blocks sit on a frictionless surface. The left block has a mass of 4 kg and the right has a mass of 8 kg. They are glued together by the dreaded, unstable, and explosive glue, BamglueTM. The glue explodes! Bam-gluey! Its chemical energy decreases by 48 J. What is the magnitude of the velocity of the left block immediately after the explosion (remember: magnitudes are never negative; if you get an answer with a negative answer, drop the sign)? Numeric: A numeric value is expected and not an expression. V =

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.
