Homework Help: Physics

Posted by Jeff on Friday, October 26, 2012 at 2:35pm.

A ballistic pendulum was a device used in the past 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 8.90 g, and the block of mass 2.20 kg swings up to a height of h = 7.70x101 cm, what was the speed of the bullet (in m/s) before impact ?
