Two 520g blocks of wood are 2.0 \rm m apart on a frictionless table. A 12g bullet is fired at 380m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.6m/s. What is the speed of the second block after the bullet stops?

According to a report on traumatic brain injury, the force that a professional boxer's fst exerts on his opponent's head is equivalent to being hit with a 5.9kg bowling ball traveling at 8.9m/s that stops in 0.018s. Determine the average force that t..
A block with mass M attached to a horizontal spring with force constant k is moving with simple harmonic motion having amplitude A1. What should be the value of the putty mass m so that the amplitude after the collision is one-half the original ampl..
