**ANALYSIS**

**HINT:** Use the **=
AVERAGE( : )** function for each data set (drop). To find s_{m
}, use **= STDEV( : )/SQRT(5)** since there are five data points
in each drop.

**2. **Find
the grand average acceleration for all 10 drops and record the result in
cell
**G77**. Average the **s**** _{m}**
values for all 10 drops and record the result in cell

**3. **Find
the average **Slope** of the **Velocity vs. Time** plots for all
10 drops, and record the results in cell **G80**.

**4. **Calculate
the percentage difference between the acceleration results and the velocity-slope
results in cells **G77** and **G80**, using the **Slope** as the
accepted value, and enter the result in cell **G84**. Answer **Question
1** on the **Worksheet**.

**5.**
Compare the accleration with the accepted
value of the acceleration of gravity, **g = 9.8 m/s**** ^{2}**,
and calculate the percentage error. Enter the result in cell

**6. **From
**Equation
(1)**, the slope of the tangent line on the Position vs. Time plot represents
the instantaneous velocity. From the 10th drop **Distance vs. Time**
Data, determine the initial velocity and record the value in cell **E104**.
From the final and initial slope data, determine the average acceleration
over the interval by using **Equation (2)**, where the acceleration
is equal to the change in velocity divided by the difference in times.
Record the value of the acceleration in cell **E106**.

**7. **Answer
**Question
2** on the **Worksheet**.
