In the ballistic pendulum shown below, the block has a mass of 1.8 kg, the bullet has a mass of 0.0057 kg, and the string has a length of 1.68 m. A bullet is shot directly at the block, lodging into the block, and causing the pendulum to swing forward 22. A ballistic pendulum is used to measure the speed of high-speed projectiles. A 6-''g'' bullet ''A'' is fired into a 1-''kg'' wood block ''B'' suspended by a cord with a length of What was the initial speed of the bullet, in m/s?"
