Need help finding the mean range and mean launch speed. The launch angle was 47 degrees. Thanks!
![### Projectile Motion Experiment Data
In this experiment, four trials were conducted to measure the range (distance) of a projectile. Each trial included three measurements of range, recorded in meters (m). The table below displays the data collected for each trial:
| **Trial** | **Range 1 (m)** | **Range 2 (m)** | **Range 3 (m)** | **Mean Range** | **Mean Launch Speed** |
|-----------|-----------------|-----------------|-----------------|----------------|-----------------------|
| 1 | 24.3 | 22.0 | 22.9 | | |
| 2 | 39.5 | 38.6 | 38.4 | | |
| 3 | 54.6 | 56.4 | 55.0 | | |
| 4 | 39.2 | 38.3 | 38.9 | | |
**Explanation of Columns:**
- **Trial**: Indicates the trial number.
- **Range 1 (m), Range 2 (m), Range 3 (m)**: The three separate measurements of the projectile's range in each trial.
- **Mean Range**: The average range calculated from the three measurements (not filled in the table and needs to be computed).
- **Mean Launch Speed**: The average speed of the projectile at launch, which is not filled in the table and presumably to be computed based on the range and other parameters discussed in the relevant educational materials.
**Instructions for Calculation:**
1. **Calculate the Mean Range:**
- For each trial, sum the three range values and divide by 3.
2. **Determine the Mean Launch Speed:**
- This typically requires additional information such as the initial angle of launch and the formula relating range and speed. This may be provided in accompanying educational resources.
**Example Calculation for Mean Range:**
For Trial 1:
\[ \text{Mean Range} = \frac{24.3 + 22.0 + 22.9}{3} = \frac{69.2}{3} = 23.07 \ \text{m} \]
**Note:** Students are expected to complete the calculations for the mean range and, if applicable, use the mean range to find the mean launch speed based on the principles of](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fefeeb880-5b7a-484d-b5c7-b5b43d8ad9f7%2Fa1410946-6f63-4ac3-8daa-07bdc2ba419a%2Fbf7sxvl.jpeg&w=3840&q=75)
