A ballistic pendulum is a device for measuring bullet speeds. One of the simplest versions consists of a block of wood hanging from two long cords. (Two cords are used so that the bottom face of the block remains parallel to the floor as the block swings upward.) A 0.013-kg bullet traveling at 320 m/s hits a 3.0-kg ballistic pendulum. However, the block is not thick enough for this bullet, and the bullet passes through the block, exiting with one-third of its original speed. Required:
How high above its original position does the block rise?

0.043 m upwards

Explanation:

The mass of the bullet, = 0.013 kg

Mass of the ballistic pendulum, = 3 kg

Velocity of the bullet, = 320 m/s

Therefore, from the law of conservation of momentum, we get

Therefore the required height to rise the block is given by :

Therefore, the block moves upwards for 0.043 meters.
