Just a quick question to start. It's really urgent as has to be handed in tomorrow (Thursday).
I have conducted an investigation involving the acceleration of a mass attached to ticker-tape.
I have drawn a Time vs Height graph, which generally shows that as time doubles, height quadrouples as expected.
However, I am confused about my first reading. It seems anomolous, but both of two readings are almost the same, so surely not!
Here is the graph:

It's the first point in question. Why is the height so high? Is it because air resistance has not yet had effect? Or do you think it could have been a problem with the experiment setup (tickertape)?
Any input would be really, really appreciated - thanks in advance for your time.
