Question

Calculate the average distances the car and the washer traveled from the top of the track. Record the average in Table A of your Student Guide.

What is the average distance the car traveled from the top of the track?

cm

What is the average distance the washer traveled from the top of the track?

cm

Answer 1

I don't have your measurement values from Table A, so I can't compute the numeric averages yet. Here is exactly how to calculate them and how to report them — paste your measurements if you want me to compute the averages for you.

Steps to calculate the average distance
1. List the measured distances (in cm) for each trial for the car. Example: d1, d2, d3, ... , dN.
2. Add them: sum = d1 + d2 + ... + dN.
3. Divide by the number of trials N: average = sum / N.
4. Repeat steps 1–3 for the washer.

Example (three trials) — purely illustrative:
- Car distances: 12.3 cm, 12.8 cm, 12.5 cm
sum = 12.3 + 12.8 + 12.5 = 37.6
average = 37.6 / 3 = 12.533... → report 12.53 cm (or 12.5 cm depending on desired sig figs)
- Washer distances: 8.1 cm, 7.9 cm, 8.0 cm
sum = 24.0
average = 24.0 / 3 = 8.0 cm

Rounding/significant figures
- Round to a sensible number of decimal places consistent with your measurements (usually one or two decimals).
- Keep units as cm.

If you paste the car and washer trial distances here (or a photo of Table A), I will compute the averages and round them appropriately.
