Question
**Question:**  
Which of the graphs in the figures below might be a plot of the vertical component of the velocity of a projectile that is thrown from the top of a building?

**Graph Descriptions:**

1. **Top Left Graph:** 
   - This graph has a downward-opening parabola. The curve begins above the horizontal axis, peaks, and then descends below the axis, resembling an inverted "U" shape. It suggests an initial positive velocity, slowing down, stopping momentarily, then accelerating downwards.

2. **Top Right Graph:** 
   - This graph shows a straight line with a positive slope starting from the origin. It indicates a constant positive acceleration, with velocity increasing linearly over time.

3. **Middle Left Graph:**
   - This graph has an upward-opening parabola. The curve starts from below, rises, and then falls back down to below the horizontal axis. It suggests an initial negative velocity that slows, momentarily stops, and accelerates back downwards.

4. **Middle Right Graph:**
   - This graph shows a horizontal line, indicating constant velocity. The velocity does not change over time.

5. **Bottom Left Graph:**
   - This graph is a straight line with a negative slope. It starts from a positive value and decreases linearly, eventually crossing below the horizontal axis. This suggests a constant negative acceleration, starting with a positive velocity and decreasing to a negative velocity.

**Analysis:**
The graph that best depicts the vertical component of the velocity of a projectile thrown from the top of a building is likely the **Bottom Left Graph**, as it shows a decrease in velocity over time due to the influence of gravity, starting with an initial positive velocity and transitioning to negative as the projectile falls.
