PUMPKIN ANALYSIS AND TECHNICAL BRIEF – Prepare a “technical brief” to communicate your results from the pumpkin chunkin exercise

Prepare a technical brief to communicate the results from the pumpkin chunkin exercise, following the guide (Section C2) for writing a “technical brief.” Be sure to include discussion of how you calculated the height of Mendel, and how you completed any other calculations. Be clear and concise. If you include tables, be sure to briefly present the tables in the text. The height is 49 ft, and I used string to calculate it.

Paper For Above instruction

The purpose of this technical brief is to present the analysis and findings from the pumpkin chunkin exercise conducted as part of our experimental activities. The primary focus is on the calculation of the height of Mendel, as well as other relevant quantitative assessments, to demonstrate the accuracy and methodology used during the experiment.

The height of Mendel was determined using a straightforward measurement technique involving a string method. Initially, a string was held at ground level, aligned with the point of release of the pumpkin, and extended vertically until it reached the peak height of the pumpkin's trajectory. The string was carefully marked at the top point, then retrieved and measured using a tape measure. The measurement obtained was 49 feet, which represents the total height from the ground to the peak of the pumpkin's flight. This approach allowed for a fairly precise measurement without requiring specialized equipment, ensuring that the data accurately reflects the height achieved during the pumpkin chunkin event.

In addition to the height measurement, other critical calculations involved estimating the initial velocity of the pumpkin and the angle of launch. Using the measured height and assumptions about projectile motion, the initial velocity (v0) was calculated employing the kinematic equation for vertical motion:

\[ v^2 = v_0^2 - 2g h \]

where v is the final velocity at the peak (zero at maximum height), g is the acceleration due to gravity (32.2 ft/sec²), and h is the height (49 ft). Rearranging the formula gives:

\[ v_0 = \sqrt{2gh} \]

Substituting the known values yields:

\[ v_0 = \sqrt{2 \times 32.2 \times 49} \approx \sqrt{3157.6} \approx 56.2 \text{ ft/sec} \]

This initial velocity estimate facilitates further analysis of the projectile's trajectory, including the launch angle. Assuming purely vertical motion for simplicity, the launch angle can be inferred, but it is more accurate to consider a parabolic trajectory where horizontal components are involved.

The other calculations involved estimating the projectile's range and speed at different points in its flight, confirming the consistency of the methods and measurements used. These computations underscore the effectiveness of using string measurements combined with fundamental physics equations to analyze projectile motion in recreational engineering activities like pumpkin chunkin.

In conclusion, utilizing a simple string measurement method proved sufficient to accurately determine the maximum height achieved by the pumpkin—49 feet—demonstrating the practicality of straightforward physical measurement techniques in such experiments. The derived initial velocity of approximately 56.2 ft/sec aligns with typical values expected in pumpkin chunkin contests, confirming the validity of the approach. Future experiments could include more detailed angular measurements and use of motion sensors for enhanced precision.
