Work Step by Step

Horizontal and vertical motion for a projectile are independent. The time to hit the floor is the same for a fast and a slow ball when they are rolled off a tabletop, and their vertical velocity components will be identical. However, the initially faster ball will hit the floor at a higher speed because its horizontal velocity component is greater. This is discussed on pages 184-185.
