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.
1) What was the average velocity of the glider when the first flag was interrupted?
2) What was the average velocity of the glider when the second flag was interrupted?
I don't get it.. What do I plug in for the displacement? Is the 25.4mm or 162mm?
How do I find the displacement with such little information?
