**Question**: As a stone falls from the building, what is true about the vertical velocity as each second passes?**Diagram Description**: The diagram shows a vertical building with four small circles representing the position of a stone at different time intervals during its fall. The circles are increasingly spaced apart as they move downward, indicating acceleration.**Answer Choices**:- ○ The vertical velocity cannot be determined.- ○ The vertical velocity does not change.- ○ It is -9.8 m/s at each second.- ○ The vertical velocity increases by -9.8 m/s every second.

Solution: Using the kinematic equation, the final velocity after one second can be obtained as, v=u+ayt =0+-g m/s21s here, u=0, t=1sv=-9.8 m/s Therefore, the vertical velocity increases by -9.8 m/s every second. Thus, the fourth option is the correct answer.
