The subject is called physics, not physic.

This is a conservation of momentum problem.
A 1.20- block of wood sits at the edge of a table, 0.720 above the floor. A 1.20×10−2- bullet moving horizontally with a speed of 750 embeds itself within the block. What horizontal distance does the block cover before hitting the ground?
