A block of mass 780 g is resting between two edges with empty space between them as shown above. A 24.0 g bullet is shot underneath the block at an unknown speed and goes through the block, leaving at 60.0 m/s. The block then “jumps” to a height of 42.0 cm as a result. What was the speed of the bullet (in m/s)?
