Now we'll keep mass at 100 kg so we can see how speed changes the number of snowmen Burt destroys.

5. Press RESET, change the spee a new number, and try again.

6. Press PLAY again and use the magic wand in the table to collect for the remaining rows.

Answer 1

Looks like some words got cut off — here’s a clean, complete set of instructions you can follow, plus a few tips for getting good data and what to expect.

Step-by-step procedure
1. Set Burt’s mass to 100 kg (leave it fixed for the whole activity).
2. Choose a speed for Burt (pick a value and enter it in the speed control).
3. Record that speed in your data table (write the number in the “Speed” column).
4. Press PLAY and watch the simulation run.
5. After the run, check the Collision results (or read the display) and record how many snowmen Burt knocked over in the “# Snowmen knocked” column.
6. Press RESET to restore the scene.
7. Change Burt’s speed to a new value and repeat steps 3–6 for each trial.
8. If the table or gizmo has a “magic wand” (auto‑fill) tool, use it to fill the remaining rows once you’ve entered enough example speeds, or to repeat a pattern of speeds.

Suggested speeds to test
- Try a range so you can see the pattern: e.g. 0.5, 1, 2, 3, 4, 5 m/s (or 1, 2, 4, 6, 8 if you prefer larger steps).
- Do 2–3 trials at each speed and average the results if the outcome varies.

Tips and expected behavior
- With mass fixed, kinetic energy = 1/2 m v^2, so the destructive effect generally increases with the square of speed. You should see more snowmen knocked over at higher speeds, often with a threshold speed below which none (or very few) are knocked down.
- If results seem noisy, run multiple trials and take the average.
- Use RESET between trials so each run starts from the same initial conditions.

If you want, tell me the speed values you plan to try (or paste your recorded table) and I can help you analyze the results or suggest the best speeds to fill in the remaining rows.
