I AP Physics 1 Vectors/Projectiles Bull's E;ye Purpose: Use your knowledge of horizontally launched projectile motion to accurately predict the impact location of a projectile. Materials: Ramp Metal Ball Procedure: Carbon Paper Meterstick Paper Tape 1. Determine the initial velocity of the ball off the end of the ramp. This can be done by doing the following: a. Tape the ramp to the edge of the table. b. Roll the ball down the ramp to find the approximate area where the ball will hit the ground. c. Tape a piece of notebook paper to the floor in this area and place the carbon paper face down and on top. d. Roll the ball down the ramp and when it hits the carbon paper, it will make a mark on the notebook paper. Do this ten times. e. You will have a collection of dots on your paper and you need to measure the distance SH and the height from the floor to the ramp, Sv. f. From this information you can do a projectile motion calculation to determine the initial horizontal velocity. 2. Calculate the horizontal distance that the ball will land if you place the ramp on the edge of the second floor and the ball travels to the first floor. The height from the floor to the top of the wall on the second floor is 5.1 meters. a. Using the velocity calculated above and the new height, perform another projectile motion calculation to determine this new SH distance. This is where the Bull's Eye will be placed. b. Your group will get one chance to hit the bull's eye. ; ¾ ,, l 0 7 ~01 Jo Ct11/y Bull's Eye goes here I I I I I I I , I ,, ,I ,I ,I ,I I .,, ,, ,, .,, ,, ,, ,, ,, ,, .,, ... .,, .,, Sv 1 ;Cll-1 (o
