The ballistic pendulum consists of a stationary 2.50 kg block of wood suspended by a wire of negligible mass. A 0.0100 kg bullet is fired into the block and the block swings a maximum height of 0.650 m above the initial position.
If you know that the speed with which the bullet is fired above was found to be 896 m/s, what would the initial speed of a bullet from the same problem above be if you know the bullet was fired horizontally from a height 1.20m and hit the ground 443m away?
