Final answer:
The 'lowest floor' in a physics context would be where an object comes to rest after being dropped, with 'V1' representing the velocity just before it hits the floor, and 'V2' after it bounces.
Step-by-step explanation:
The question refers to a scenario in physics where an object, in this case, a phone, is dropped from a certain height and interacts with a floor. However, it seems that there might be a confusion with the term 'V Zone,' which typically relates to a flood zone designation in coastal areas, under Federal Emergency Management Agency (FEMA) regulations. In physics, especially when discussing the mechanics of falling objects, the 'lowest floor' would be where the phone ultimately lands and comes to rest. Looking at the velocities mentioned, Vi would be the velocity just after the phone is released (zero for a drop), V1 would be the velocity just before the phone hits the floor, which would be at its maximum downwards speed, and V2 would be the velocity after bouncing, indicating the upward speed of the phone post-collision.
