4. Release the cart from rest and use the stopwatch to time how long it takes the cart
to reach the end stop. The person who releases the cart should also operate the
stopwatch. Repeat this measurement 10 times (with different people doing the
timing). Record all the values in Table 8.1.
5. Lower the end of the track by 1 cm and repeat step 4. Use the same release posi-
tion.
6. Repeat step 4 for a total of 7 angles, lowering the end of the track by 1 cm for
each new angle.
Data Analysis
1. Calculate the average time for each angle and record it in Table 8.1.
2. Calculate the distance traveled, d, from the initial to the final position.
3. Use the distance traveled and average time to calculate the acceleration for each
angle and record it in in Table 8.2.
