For example if I move 5 meters in 5 seconds my velocity is 1m/s, then for acceleration I put 1m/s over 5s, then my acceleration is 0.2m/s.

It is average acceleration sorry, for instantaneous acceleration use dv/dt and velocity use dr/dt.

What you need to do is find the average speed between each pair of marks: distance measured on the tape divided by the time interval.

Now do the same for each pair of average speed values: subtract the two speeds and divide by the time interval.

That gives the average acceleration over each interval and gives you an acceleration function between intervals.

i figured out that the graph of the instananeous velocity of vs teh time at that speed will give me the slope equal to the acceleration. if i still sound confused please help but thanks for your replies!
