6.[1pt] tit Hint: This is a problem in two parts! When the bullet hits the wood, it's an inelastic collision problem. When the block swings up, it's an energy problem. Is energy conserved in both the collision and the swing up? Is momentum conserved? ...... l..- __________ in..." h A ballistic pendulum, as shown in the gure, was a device used in the nineteenth century to measure the speed of bullets. The pendulum consists of a large block of wood suspended from long wires. Initially, the pendulum is at rest. The bullet strikes the block horizontally and remains stuck in it. The impact of the bullet puts the block in motion, causing it to swing upward to a height h. If the bullet has a mass of 8.2 g, and the block of mass 2.3 kg swings up to a height of h = 60.0 cm, what was the speed of the bullet before impact? Answer: Submit All Answers ->
