Case 1You and your friend are driving on a road trip to the beach, 120miles away. You leave at 12:00 noon, and when you are 10minutes away from the beach, you see that you’re also at milemarker 10.At that moment, your friend gets pulled over by the police forspeeding.“Speeding?” your friend says—that can’t be. I left at noon, andI’ve driven 110 miles so far, for 110 minutes. So my velocity isjust: v = ∆X = 110 mi = 1 mi = 60 mi ∆t 110 min min hSince the speed limit is 65, you shouldn’t give me a ticket.
Case 2You get a speeding ticket for speeding on the highway, and whenyou ask the officer why, he says, when I looked out my driver’sside window, I saw your car. This means you were speeding.

InstructionsEach group should choose 1 side of these 3 cases (ticket/noticket).Make your best physics case on a whiteboard for why you do/don’t deserve a ticket. Good cases include graphs, diagrams, andexplanations.If you decide your case is flawed, and you’re on the wrong side,figure out why someone would believe your case, and try to makea case from that. Push the other team to convince you that you arewrong—don’t roll over and play dead.Hold a mini trial to argue either side of the case.
