In the lab mode, set the cannon to fire at 30 degrees from the horizontal. Make sure air resistance is turned off. Set the cannon speed to 10 m/s and fire! Use the range field of the inspector crosshairs (discussed in the first video) to measure how far it went. Let's call this distance D10 Now double the speed, increasing it to 20 m/s. What do you think happens to the distance traveled? Does it double? Less than double? More than double? Try it out and record how far it went. Let's call this distance D20 Now, how many times farther did it actually go? Please round your answer to three D20 significant digits. This answer should be the ratio of distances traveled: D10 Now, fire the cannon at 15 m/s at an angle of 30 degrees. Use your crosshairs to measure its landing position and take a screenshot. Please paste your screenshot

Use the range field of the inspector crosshairs (discussed in the first video) to measure
how far it went. Let's call this distance D10
Now double the speed, increasing it to 20 m/s. What do you think happens to the distance
traveled? Does it double? Less than double? More than double? Try it out and record how
far it went. Let's call this distance D20
Now, how many times farther did it actually go? Please round your answer to three
significant digits. This answer should be the ratio of distances traveled: P20
D10
Now, fire the cannon at 15 m/s at an angle of 30 degrees. Use your crosshairs to measure
its landing position and take a screenshot. Please paste your screenshot
