Does anyone know what the formula is for working out the velocity or displacement?

Ohh. I'm with you now. Yeah that would make sense seeing as I need to add the average velocity also. It was like 11pm when I went to bed. Big time different.

I'm getting confused again. I don't even remember/know why we're trying to work out 0.15 seconds. =S Anyway, I've got to go to bed so i'll be back tomorrow morning or tomorrow afternoon. Thanks for helping. =)

I don't get why we start at 0.15 s and not at like 0.05 s. Plus, how did you get 57cm/s? (Try to dumb things down ALOT hehe) I don't really know what half of this stuff is such as delta y's, gradient and delta x.

So.. 0.1 seconds = 2cm 0.2 seconds = 7.7cm (5.7cm + 2.0cm) 0.3 seconds = 17.5cm (9.8cm + 5.7cm + 2.0cm) 0.4 seconds = 31.5cm (14.0cm + 9.8cm + 5.7cm + 2.0cm) 0.5 seconds = 48.9cm (17.4cm + 14.0cm + 9.8cm + 5.7cm + 2.0cm) 0.6 seconds = 69.9cm (21.0cm + 17.4cm + 14.0cm + 9.8cm + 5.7cm +...

No. I don't really have any clue what your talking about there, sorry.

The displacement graph? I haven't done a displacement graph though. If I had a displacement graph, that would tell me what I want to know. I think. =S

The second point is 98 cm/s, yes, but how do you get the 1.15 seconds? How does this help tell me the displacement?

For the second section I've got 5.7cm>57cm/s>370cm/s I went 57 - 20 = 37 x 10 = 370cm/s

I'm trying to find the average displacement. Or do I have it already? =S I measured it so that I had 5 spaces inbetween the dots. So every 6 dots I started a new section. I continued the next section from the ending section of the last if that makes any sense.

I understand everything you've just written there. Yep that seems right to me.

Well I have 0.1 seconds for time (cant remember how I got it but it was divided by something off memory). The length of my first section of the first tape is 2cm. From that I've gotten average acceleration of 200cm/s. I multiplied the 2cm by something to get the 200cm/s. I done it a while ago...

The average acceleration for tape 1: Sections: 1)200 2)370 3)410 4)420 5)340 6)360 7)-160 The average acceleration for the whole of tape 1 is 277.14

I'm not really following, sorry. I'm just getting really confused now. I'm not sure what you meant about the average acceleration and I'm also not sure as to why you quotes what I said. I attatched my work so far if you want to have a look at it. I'm probably confusing you ALOT.

"The average acceleration values that you've got are then for each such group of five dots?" I don't mean do be annoying or anything, but what do you mean? I don't think I actually mentioned this but I'm using a ticker timer. My ticker tape is roughly 1m long on each of the tapes. I used...
