using a ticker timer and ticker tape. timer started when trolley 1 was released and stopped when the trolleys were stopped at the end of the runway

hi ok so I presume you know the rest of the experiment so basically its this: "when you gently push the first vehicle, it passes through the first photogate and the dual timer records t1 (1st time). When the two vehicles coalesce and move together they pass through the second photogate causing the dual timer to read t2 (2nd time). you then calculate the inital velocity and the final velocity hope that helped / made sense :)
