Problem

A 12 g12\,\text{g} bullet traveling 500 m/s500\,\text{m/s} horizontally embeds in a 1.5 kg1.5\,\text{kg} block that is initially at rest on a frictionless horizontal surface. What is the speed of the bullet–block combination immediately after the collision? (a) 0.40 m/s0.40\,\text{m/s} (b) 4.0 m/s4.0\,\text{m/s} (c) 3.3 m/s3.3\,\text{m/s} (d) 4.5×101 m/s4.5\times10^{1}\,\text{m/s}
