a ballistic pendulum is a device used to measure the speed of a bullet. A bullet of mass m = 50g is fired at a block of wood (mass m =750g) hanging from a string. The bullet embeds itself in the block, and causes the combined block plus bullet system to swing up a height h=0.45m. What is the initial speed of the bullet before it hits the block?

In a device called the ballistic pendulum, a compressed spring is used to launch a steel ball horizontally into a soft target hanging from a string. The ball embeds in the target and the two swing together from the string. Describe the energy transfers and/or transformations that take place during the use of the ballistic pendulum and at what points they occur.

A bullet of mass m = 2.40×10-2 kg is fired along an incline and embeds itself quickly into a block of wood of mass M = 1.35 kg. The block and bullet then slide up the incline, assumed frictionless, and rise to a height H = 1.35 m before stopping. Calculate the speed of the bullet just before it hits the wood.

Can someone explain: The ballistic pendulum is an apparatus used to measure the speed of a projectile. An 8.0 g bullet is fired into a 2.5 kg ballistic pendulum bob, which is initially at rest, and becomes embedded in the bob. The pendulum then rises to a vertical distance of 6.0 cm. What was the initial speed of the bullet (in m/s)?
