For Lab 2please Review Chapter 3 In Your Textbook This Lab Involves

For Lab 2, please review Chapter 3 in your textbook. This lab involves a projectile being fired upward at an angle to the horizontal. You are to program the spreadsheet Excel (a similar substitute software program is permissible) to determine the maximum injection angle, that will result in the greatest downrange distance, R. Assume v = 10 m/s and g is approximated as g = 10 m/s2. Fill in the data table, and answers for the blanks and complete the graph (properly labeled and θmax annotated) in the Lab Answer Sheet at the end of this lab. {Hint: watch out for conversion problems from radians to degrees in Excel}.

Paper For Above instruction

This laboratory exercise is centered on analyzing projectile motion, specifically, determining the optimal launch angle that yields the maximum horizontal distance, known as the range. The physics of projectile motion is well understood, governed by the equations of motion under constant acceleration due to gravity, and offers a practical application of kinematic principles within a laboratory or computational setting.

The primary objective in this experiment is to utilize spreadsheet software such as Microsoft Excel to simulate and analyze the projectile's trajectory. By programming the appropriate equations, students can compute the range of the projectile for various launch angles, thereby identifying the angle that produces the maximum distance traveled horizontally. This process not only reinforces theoretical understanding but also enhances practical skills in data analysis, graphing, and understanding the importance of unit conversions in computational models.

Given initial conditions—namely, an initial velocity (v) of 10 m/s and gravitational acceleration (g) approximated as 10 m/s2—students will systematically vary the launch angle (θ) from 0 to 90 degrees. For each angle, the horizontal range R can be calculated using the equation:

R = (v2 / g) * sin(2θ)

In the spreadsheet, students should ensure the conversion of angle measurements from degrees to radians, as Excel’s trigonometric functions operate in radians. The process includes setting up columns for angles, conversion to radians, calculating the sine of twice the angle, and then computing the corresponding range.

The data gathered through this simulation allows for plotting a graph of range versus launch angle. The graph should be appropriately labeled, with the maximum point (θmax) clearly identified and annotated. This visual representation aids in understanding the relationship between launch angle and range, confirming the theoretical result that the optimal angle for maximum range in projectile motion, under ideal conditions, is 45 degrees.

Additional considerations include checking for proper unit conversions within Excel and confirming the correctness of formulas. Students should pay particular attention to potential errors due to radians-to-degrees conversions. The final step involves filling in the data table, identifying the maximum range and corresponding angle, and completing the graph accordingly, adhering to lab reporting standards.
