Projectile motion — lab write-up

Use the data from the launch we recorded on Tuesday. Include your error bars; a graph without them is a guess.

Method, results, discussion. The method should be short enough that somebody else could repeat the launch from it, and no shorter. Put the timing-gate spacing in, because two groups used a different setup.

For the discussion, compare your measured range against the prediction and account for the gap. Air resistance is a real answer; so is a badly levelled ramp. Guessing is not.
