In a ballistic test, a small bullet is projected at a wooden block hanging from a light string. The 40.0 gram bullet is launched horizontally at 650.0 m/s. The 3.50 kg block is initially at rest. After the collision, the bullet is embedded in the block and the block-bullet system moves with a non-zero speed. What is the speed of the block-bullet system immediately after the collision? (Ignore air resistance) 8.41 m/s 7.34 m/s 26.0 m/s 650.0 m/s
