Part 2: Equipment for Part 2: 2 V-channels 2 Wooden blocks with cut outs Ring stand Metal ball Carbon paper Wooden board Procedures for Part 2: Now the projectile will be launched over an angled surface and you will determine the distance the ball will travel along the angled surface. You will not use video analysis. V-channels VO Metal Ball Wooden Board with carbon Ring Stand paper on top Wood Blocks Lab Table 1. Measure the height above the floor that the ball will leave the V-channel: 0. 94 m 2. Without using the wooden board, set the carbon paper on the floor where the ball will hit. Release the ball from the exact same spot five times and let it hit the carbon paper on the floor. Measure the horizontal distance from the edge lab table to the mark on the carbon paper where ball hits the floor each time. Record the data below. Find the average horizontal distance that the ball travels when released from this location. Average horizontal distance: $6 . | 1 0.95 cm H = 0.9 4 3. Use the height and average horizontal distance to show your work and calculate the initial speed the ball leaves the table: run times 0. $6 m Jd = 0 0. 56 7 m Initial speed: 1 295 10 m/s 0. 56 1 m 4 0.567 m 0 . 56 1 m 284. Tape the same piece of carbon paper to the board and place the board against the table. The top edge of the board must just touch the end of the V-channel. The paper must start right at the bottom of the V-channel, and not at the height of the table. Measure the angle of the board from the horizontal: 19 + 0.50 5. Using the initial speed, angle, and equation derived in the predictions; calculate the predicted distance the ball will travel along the board. d= 2 vo Sino 9.81 Cos20 2 (1. 295 ) sin ( 19" ) 9.81 Cos 2 ( 490 ) Predicted distance: 0.519 m = 0.599 m 6. Release the ball from the same spot as #3. It should hit the carbon paper and make a mark. With this mark you can measure the distance along the angled board that the ball hits. Repeat this measurement ten to fifteen times total. Record these measurements below.

Each measured horizontal distance and distance along the incline had uncertainty. Explain what uncertainty was used for those values and why. measurement uncertainty. because these uncertainties are made by measuring instruments 2. Repeating the measurement of the horizontal distance and distance along the incline should reduce their uncertainty. Show work to propagate uncertainty in the average distance. 293. Show work to propagate the uncertainty in the initial velocity. 4. Show work to propagate the uncertainty in the predicted distance along the incline. 5. Compare the average measured distance that the ball traveled to the predicted distance that the ball would travel, using uncertainty. Explain any differences. Conclusions: 30
