Question

3.) MATH: Show mathematically that R is maximum for 8-45 for this h-0 case 4) CONCEPTS Let's now soescsetsalk explore why all 0 45 produce less range (for he-o) The three initial velocity vectors below are all of the same size, indicating the same launch speed However, the launch angles are varied. Vi Vi 0-45° Case I c45 Case II e>450 Case III a.) In the figure above, draw (to sale) the horizontal (v.) and vertical (V.,) components for each of the three initial velocity vectors. b.) Which case has the largest xertisal ylocity (V,)? the largest flight time? cuse III Circle one.) (Circle one.) Largest viy caseI case II Largest flight time: case I case II case Il Why dossn't this case have the maximum range? Explain conceptually. In your response, cite the launch angle (0" θ 90°) that would have the lnesrfightame, and its corresponding range. (Also fill them in on the right.) For max flight time: Lab#3: Projectile Motion-p.8
