investigating Angie 1. Use the C-Clamp to secure the mini launcher near the edge of the table such that the ball will have room to travel once launched. - *- Launcher Sketch of Mini Launcher at Edge of Tobie 2. Position the launcher such that it is horizontal, with a 00 angle. Use the push rod to press the ball into the launcher until you hear 1-2 clicks; each click results in more force to launch your projectile. Use the pole cord to release the ball and observe how the system works. 3. Choose 3 non-zero angles from which you will release the ball and "it these angles in the "Angles & Distance\" data Table. 4. Rank the angles from 1-3, predicting which launch distance will be the greatest (15') to the least (3\"). Add your ranking to the "\"Angles & Distance\" data Table. 5. Launch the steel ball from each angle, using the same number of clicks each time you load the launcher, and record the distance the ball travels (how far from the launcher does it hit the ground). You will need to watch carefully for where the ball lands and measure the distance it travelled. Record 3 trials of data for each angle in the \"Angles & Distance\" data Table and then calculate the average distance for each angle.

If the steel ball had been launched from halfthe height ($31), what would happen to the time (t) to drop and horizontal range (x) for the steel ball?

Launch the ball 3 times using the same number of clicks that were used to find the average velocity (v) ofthe ball. Measure and record the landing distance, the horizontal range ofthe ball in 'x'. Record 3 trials of data in the \"Horizontal Range\" data Table, even if you hit the can each time. Calculate and record the average exgerimental range of your ball. Determining Range 6. Measure and record the vertical distance 'y' in meters that the ball must drop from its release point to a can on the floor. Do not attempt to launch the ball into the can yet. illustration of ball being launched and following curved path to can 7. Position the launcher so it is horizontal, parallel to the ground, with a 0 angle. Hold the photogate in front of the launcher such that the ball will pass through the photogate when launched. Make sure the setting on the photogate is m/s and practice 2-3 launches of the ball through the photogate. 8. Launch the steel ball using the same number of clicks each time you load the launcher and record the launch speed 'v' of the ball shown by the photogate.

Predict the distance in meters your ball will travel once launched, the horizontal range. Enter your prediction in the \"Horizontal Range\" data Table. " 9'- ' 10. Calculate the time (t) for the ball to drop from the launcher to the floor, to drop the vertical distance 'y' that you measured. Then calculate the horizontal distance 'x' the ball should travel, the horizontal range. Record your calculated horizontal range in the \"Horizontal Range\"dataTable. O rL-l S
