A thin block of soft wood with a mass of 0.072 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is red with a speed of 619 mfs at a block of wood and passes completely through it. The speed of the block is 17 mfs immediately after the bullet exits the block. (a) Determine the speed (in m/s) of the bullet as it exits the block. mfs (b) Determine if the final kinetic energy of this system (block and bullet) is equal to, less than, or greater than the initial kinetic energy. equal to the initial kinetic energy less than the initial kinetic energy greater than the initial kinetic energy (c) Verify your answer to part (b) by calculating the initial and final kinetic energies of the system in joules. KEI- = J KEf = J
