Before electronic timing devices were developed, a ballistic pendulum was used to measure the speed of bullets. The bullet imbeds in the block and the energy of the block/bullet system raises the system to a certain height. Conservation of momentum and conservation of energy must be used because mechanical energy is not conserved. Determine the speed of the bullet if the mass of the bullet is 10 g, the mass of the block is 6.0 kg and the bullet/block system is raised by 6.3 cm (h).
