PHY-221: Physics 1Spring 2024 Lab #8Projectile Motion Overview Projectile motion is the motion of an object projected, thrown, shot, or launched at either a horizontal (zera) or general (non-zero) launch angle. Once in motion in the absence of air resistance, the object moves simultaneously vet independently in the horizontal and vertical directions subject only to the acceleration due to gravity. This lab will make use of the characteristics of projectile motion and the kinematic equations for projectiles to tell us something about the motion of .. jumping goats! Instructions 1. Watch these videos about projectile motion: a. Professor Dave Explains Projectile Motion: hitps:/yvoutu.be/a 822q044WA b. PROJECTILE MOTION | Physics Animation: https:// f 2. Watch this short video of our jumping goats: https:/voutu.be/oRCRtubFh14 Analysis Answer the following questions: 1. 'What minimum launch speed must the goats have to Rnge Equhon ensure a safe landing? HINT: The range equation may be helpful here. ruz sin (2 9[} ) 2. What maximum height do the goats reach? R _ U 3. How long are the goats in the air? q Assume the following in your solutions: * The goats must clear a 4-meter wide crevasse to land at the same height on the cliff on the opposite side. The goats jump at an angle of 30 to the horizontal. = All goats have the same mass and height. That means that the quantities calculated are the same for all goats. Submission This lab will be submitted as a narrated slide presentation. The finished product should be a recording in which vou (in your own voice) walk me through your solution with the narration of no more than six slides in 4 minutes or less. Pretend that vou're explaining vour solution to someone who knows about projectile motion but is interested in how you arrived at your answer. Show equations and results. This can be accomplished in a variety of ways, and you can choose the one that works best for you: Marrated PowerPoint presentation (preferred if you have access to PowerPoint). Marrated Google Slide presentation (requires uploaded audio file). Recorded Zoom presentation. Recorded Google Meet presentation. Recorded ScreenPal presentation (free download). Other ways? [ am open to ideas. If you have a tip or suggestion, let me know! &L Al
