University of Colorado – Colorado Springs Projectile Motion Name: Braden Baker Objective This lab’s goal is to represent and experiment with two-dimensional kinematics. To create data, a ball was launched with various equipment present to assist in creating comparisons to the ball’s time of flight and the range it travels, depending on the angle of launch. Projectile Motion Data 1.) Include all needed data from capstone file. 2.) Measure value for the initial launch height (y o ). 0.06 – 0.01 y o 0.05m

Show at least one example of your calculated Time of Flight and Range values. (Use your results from Prelab question #3) At angle 10: t= [-(3.4)sin(10)+ √ (3.4sin10)^2 - 4(1/2)(-9.81)(.078)]/-9.81 = 0.170999 x= 3.4cos(10)(0.170999) = 0.573 3.) Fill in the blanks of the general kinematic equations with the coefficients you measured for each angle. Projectile Motion - 2

P E S 1 1 6 0 - A D V A N C E D P H Y S I C S L A B I Y = 0.1x +0.2 a. Using the graph above classify the validity of your experiment?  General consistency between the experimental and theoretical values.  Describe areas of discrepancy. Both lines generally follow the same consistency and pattern, however the calculated, theoretical values are more linear than the tested experimental values, most likely due to errors regarding the equipment’s ability to perfectly yield results each test.

P E S 1 1 6 0 - A D V A N C E D P H Y S I C S L A B I 2.) Plot the experimental Range and the theoretical Range vs. the launch angle. Y = 0.4x + 0.8 a. Using the graph above how would you classify the validity of the experiment?  General consistency between experimental and theoretical values.  Explain areas of discrepancy. Both lines follow the same general path, with a few discrepancies near the end, most likely due to an inaccurate measurement of where the ball precisely landed.

P E S 1 1 6 0 - A D V A N C E D P H Y S I C S L A B I Conclusion (It’s up to you to fill this one out.) This experiment proved theoretical relationships between angle, velocity, time of flight, and range of a metal ball launched in the air. Data proved fairly accurate, even considering the inaccuracy of certain measurements, such as distance travelled. The approximate angle to reach a maximum range was around 40 degrees.
