##### Reference no: EM13543611

Two blocks of identical wood sit on slippery (no friction) ice. You fire a bullet at each block. At the first block, you fire a metal bullet that impales itself in the block. At the second block, you fire an equal-mass, equal-speed rubber bullet that bounces straight back from the wood block. Which wood block if either will have the greatest speed after the collisions? Please explain your reasoning!
