Shared evidence
Supplied / recorded data table
| t (s) | x (m) | y (m) | vx (m/s) | vy (m/s) |

Calculate before revealing
The partial vy–t graph stops at 1.5 s. Determine when it should end at the ground. Record L1.1–L1.5 below before testing a release point.
Revise the model
The solid vx–t line comes from the supplied record. The dashed line is the team’s no-wind prediction. This extension uses constant horizontal acceleration, not an air-speed model.
Use your match evidence
Start or resume the separate Earth lab match. Before locking orders, select a cannon or carrier attempt and record predictions digitally or on paper. Return after the round finishes.
Open Earth 1v1 lab match →Controlled practice revision
Uses the recorded field and both original orders. Cannon changes apply to that crew’s shared firing settings; disclose this limitation if more than one cannon fires. Carrier changes alter release position. All other settings are held.
Device / usable-record fallback
Use the supplied L2 miss and your tested corrected-release run for L3. Label both as supplied-model evidence on paper. This fallback is not a match record. It can earn reasoning credit without a match win.
Individual transfer
Respond independently on the final worksheet. Keep your original answer beside any correction. A partner’s game result does not replace this response.
Original prediction, result and revision
| Evidence | Original selected attempt | Practice revision |
|---|
Prediction error is signed: recorded x − predicted x. Target miss is recorded x − target x. An off-map exit is not a measured impact. First contact is recorded separately from crater formation, bounce, skid and later motion.
Individual response record
Use the numbered paper questions for equations and G.U.E.S.S. work. Type a response here or acknowledge that the matching question is on your paper. First responses remain available after corrections.
