12:2766∘ b) What is the vertical component of the acceleration of the ball after it leaves the gun when it is fired horizontally? Neglect air resistance. Put in a numerical value. 27 c) What is the horizontal component of the acceleration of the ball after it leaves c) What is the horizontal component of the acceleration of the ball after it leaves the gun when it is fired horizontally? Neglect air resistance. Put in a numerical value. 28 the gun when it is fired horizontally? Neglect air resistance. Put in a numerical 29a=m/s2 d) When determining the distance the ball traveled, it should be measured from 30 the same point on the ball in the initial and final position. What part of the ball marks the paper on the floor: front, bottom, or back? 31 e) From what point on the ball should your measurement start when the ball is loaded in the gun: front, bottom, or back? f) When measuring the initial position of the ball, should the gun be in the cocked or un-cocked position (where does the ball become a projectile)? 6. In the next step, you will be recording data on a data sheet. Do no calculations before recording the numbers. Use the table on the next page as your data sheet. Read and record all distances to the closest 0.1 cm. 36 7. Measure and record on the next page the height of the ball above the floor when it is loaded in the gun to get the initial height of the ball. 8. Measure the horizontal flight distance in cm of the ball for each run. 9. Once you have all of your horizontal flight distances, remove the white sheet from the floor and return the carbon paper. 37 HORIZONTAL FIRING ANALYSIS - Each person must do all of the following steps. Work independently and compare numbers to eliminate mistakes. 38 1. Complete the table below by doing the following: 39 a. Calculate the mean (average) distance for the 10 firings. b. Calculate the deviation of each run from the mean. Note that the deviation is the distance for that run minus the mean distance. Deviation can be positive or negative. 41 c. Calculate the mean (average) of the deviations. d. Ideally, what should the mean of the deviations equal? Put
b) Apply the equations using the ball's initial height and mean horizon distance to find the initial speed of the ball (when it becomes a projec the gun). Show all of your work in the space below: equations used, al numbers and units. Do the calculation once using the mean (average) distance. Please do your work in pencil.

General Procedure - In this section you will use the SAME gun and range setting that you used for the horizontal firing. This time you will fire the gun straight up. You will use the average maximum height reached by the ball to calculate the initial speed of the ball. B. Detailed Procedure 1. Turn the gun until it is pointed straight up. Prop a two-meter stick up next the gun. The stick should be oriented vertically, with the zero mark touching the fxx​ Enter text or formula
