ok were doing a lab

h t t p: / /i m g2 0 0. i m a ge s h a c k. u s / im g 2 0 0 / 30 3 8 /s k e t c h 2 p q g. j p g

the timer in the picture makes a mark on the tape at a set interval...

my question is well what is actually is happening is that I'm pulling the tape sense I'm taller then the table my arm isn't going to be pulling the tape straight out it'll have an x component and a y component

does this effect the data at all...

I can't decide because the distance is being measured through the timer which only has an x component and no y...

I can't make up my mind like if I pulled the tape with like a 90 degree angle with the surface it sits on would that matter???

What is important is the rate at which you pull the tape, since the timer makes a mark at regular (time) intervals. The angle is not relevant as long as the tape comes out at the required rate, 1 ft/sec. or whatever. The angle will make a differnce in the force required to pull the tape. If the tape is perfectly flexible like a string, and there is a roller to change the direction of the tape, even the force will not make a difference.
If I have not understood your question, please send more clarifications.
