A glider on an air track moves in the +x direction with a constant acceleration. It has two flags, each exactly 25.4 mm long, with the midpoints of the flags separated by 162 mm. The first flag interrupts the photogate timer for a time 50 ms, and the second flag interrupts the photogate timer for a time 45 ms.
what was the average velocity of the glider when the first flag was interrupted?
Approximately how much time elapsed between the passage of the first flag and the passage of the second flag?
(i don't really know how to start on it.)
thanks!!
