Here are the graphs showing the rock's position and velocity over time:

1. Position Graph: This graph represents the rock's position (measured as the distance from the top of the building). The position initially decreases as the rock moves upward, then reverses direction as it falls back down, ultimately approaching the ground level.

2. Velocity Graph: The velocity starts as positive (upward) and decreases to zero at the apex (highest point). Then, the velocity becomes negative as gravity accelerates the rock downward.

Would you like further details on any specific part of these graphs?

Here are five related questions to expand on this topic:

1. What happens to the position graph if we change the initial velocity of the rock?
2. How does the velocity graph change if the gravitational acceleration varies (like on different planets)?
3. What is the effect of measuring position from ground level instead of from the top of the building?
4. How can we calculate the time it takes for the rock to reach its peak?
5. At what time does the rock hit the ground, and how can we calculate this?

Tip: Always identify your reference point when measuring motion, as it affects the interpretation of position and velocity graphs.
