**Prelab Worksheet**  
*(Completing this section will make the lab easier for you).*

1. If the measured length of the pendulum from the pivot point to the center of mass is 20 cm, and the cup pivots 25° after the ball is shot into it, then determine Δh. (Hint: use the Trigonometry Equation).  

**Diagram Explanation:**

- This diagram shows a pendulum system with a pivot point at the top.
- The pendulum arm length is labeled as "L" and is represented twice to indicate its position before and after the ball is shot into the cup.
- The angle of pivot, "θ", is given as 25°.
- The "Center of mass when ball is in the cup" is marked with a red arrow.
- The change in height, "Δh", is represented by a vertical red line between the initial and final position of the center of mass.
- The diagram is a side view illustrating the effect of the angle on the height change. 

To solve for Δh, you will apply trigonometric principles using the given angle and length of the pendulum.
