I have a question regarding paper 3. When drawing a graph based on the readings on our table, if one of our points is far off from the others, after circling it, should we repeat for the reading by crossing out our previous results on the table and just write the new results above the previous one? Or add a new row? Or do we not repeat at all?

If there's only one point that is deviating from all the other points, you just have to circle this point and indicate that this is the anomalous point. You don't have to repeat it. However, you can't have two or more points that are way off.

Can you answer my question now? :) The one I posted above.

Use the equation of motion s = ut + 0.5at^2
Now substitute the data into the equation
For XY
S= 40
t=12
u=??
a=??

equation 1 : 40 = 12u + 72a

For the X to Z
S= 80
t= 18
a=??
u=???
equation 2 : 80 = 18u + 162a
Why not I use the distance Y to Z is that it unitial velocity is different from that of X to Y
Now use simultaneus equation to get the answer..

Yeah, did it the same way.. (y)
