Section Date Molly Name CONCEPTUAL PHYSICAL SCIENCE Experiment Gravity, Projectilei, and Satellites A Projectile Puzzle You Can Solve Wo Bull's Eye Purpose To predict the binding point of a projectile Apparatus Imipervikk mean of projecting the wocel ball horizontally at a known velocity Discussion Figures 415-4 17 in Conceptual Propical Somnce show how projectiles move with cortant speed in the horizontal direction while undergoing lice fall accelention in the workand dinection. Figure 1 at the right sheet the wme for a bul totied ho tribal by The horizontal and vertical motions are independent of each other! Figure 1 Inseed of towing a bull from a chill, you'llfred bel bull off the edge of a cable and into a can on the floor below-all without a trial shot! When engineer build bridges on apicrape, they do not do wo by trim and error, For the upbonol wifety and economy, the effort munt be right the Not time Your goal in the experiment b to predict where a steel ball will Lind when projected horizontally from the edge of a table. The final test of your measurements and competitions will be to pookion an empty can so that the ball lands in the on on the finif attempt. Procedure Step 1: Your Instructor will provide you a means of projecting the steel ball at a known horizontal wildcity Of mine bea spring gun acamp, or some other device). Position the bill projector at the edge of a table so the ball will Land downrange on the lieor. Donot make any practice thats (the fun of this experiment is to predict where the ball will land without seeing a bis). Figure 2 shows the quintiles involved in this experiment. mit bil BULLS MEYou will be given the laltial speed of the steel ball for perhaps you'll have to devise a way tome Itj, Record the firing ipeed here. 3DH3152 14212YH9 JAUT93503 Horizontal speed ve, Step 21 Carefully measure the vertical distance y that the ball must drop from the bottom end of the ball projectof in order to land in an empty soup can on the Boor, Be sure to take the height of the can Into account when you make this measurement. Vertical ditangry's Step 3: The vertical free fall motion is governed by the equadony= [lodge. A rearrangement of the equation, to wizygi enables you to calculate the time it takes the bell to fall from its original height for gravenional acceleration, use g - 530 cmis' Time of flight ! =_ Step 4: The range is the horizontal distance a projectile travels, I Predict the range of the ball using aww. Write down your predicted range. fed late wid prithsong to ancam Predicted ranges=. Now place the can on the foor where you predict it will catch the ball Step 5: Only after your inorvasc has checked your predicted range and your can placement, shoot the bell Summing Up L.
