Apparatus setup The sketch of PASCO 850 interface is given in the "Introduction" of this lab manual. 1. Connect the photogate 1 to Port 1 and the photogate 2 to Port 2 of the Digital Inputs on 850 Interface respectively (Fig. 2). 2. Measure the mass m and the diameter d of the steel ball. Record the data in Table 1. = 3. Stick a Velcro pad to a steel ball and measure its dimension d, - d+the thickness of one Velcro pad. Record the data in Table 1. 4. Stick a Velcro pad to each of two balls and stick them together, then measure the dimension of the 2- ball system d, -2d+ thickness of two Velcro pads. Record the data in Table 1. 5. Unscrew and pull out the guide bar outward until the center of the ball #1 at position A is just touch the mark h₂ on the guide bar as shown in Fig. 2. 6. Measure and record h, and h₂ accurately using a 15 cm ruler and record h=h₂ -h, in Table 1.

total Work to be done: 1. Print Graph Page #1(similar to Fig. 3) 2. Click "Print" icon in the Tool Bar, select # of pages to be printed, click "print" at the bottom. Let your TA check your Graph Page #1. If it is OK, your TA will sign it Caution: Make sure that your pristed Page #1 is OK before you close the Capstone. All the data collected in Experiment 6 will be lost when the Capstone is closed 3. Close PASCO Capstone by clicking the red-cross at the upper corner, then select "discard" 4. Turn off PASCO 850 interface and shut down the computer. 5. Clean up your bench. Data analysis 1. Calculate <>ie, the average value of the three mean values in columns 1, 3 and 5 in Table on Graph Page #1. Record the calculated data in Table 2. 2 Calculate <>, Le, the average value of the three mean values in columns 2, 4 and 6 in Table on Graph Page #1. Record the calculated data in Table 2 3. Calculate <>, Le, the average value of the three mean values in columns 7,9 and 11 in Table on Graph Page #1. Record the calculated data in Table 2. 4. Calculate <>.Le, the average value of the three mean values in columns 8, 10 and 12 in Table on Graph Page #1. Record the calculated data in Table 2. Table 2 Measured average time of balls) passing the photogates <> (8) <> (5) > (1) 0.0/+31 <> (1) C-1126 00220 5. Use data in Tables 1 and 2 as well as Eqs. (4) and (7) to calculate the speed(s) of the ball(s) before and after elastic/inclastic collision. Record the results in Table 3.
