A ballistic pendulum is a device that historically was used to measure the velocity of bullets. This system consists of a block of wood suspended by cords of negligible mass. When a bullet strikes the block of wood, the bullet burrows into the wood and comes to rest by frictional processes. The block and bullet combination then swing upward to a certain height, where it is momentarily at rest before swinging back down. Given the above, answer the following: If a 30.0g bullet is fired into the 5.0kg block and the combination rise to a height of 6 cm, a) What is the maximum potential energy the block and bullet combination can achieve? b) What is the velocity of the bullet before it strikes the block of wood?
