For the Scan attachment:
The question asks me to find the maximum acceleration. I used those two points in red in the attachment to calculate the gradient doing difference in y and difference in x. I got 4m/s ^2: does it seems correct, or I should have to tangent it? Because it seemed to be a straight line to me.
The next part of the question asks me to draw the general shape of an acceleration time graph from that velocity time graph. (Answer in reply attachment). I divided the graph in four different parts. In the first section it is accelerating non linearly from 0 to 2.2. I think that line is correct. The second part, from 2.2 to 3 I drew a steeper straight line upwards but I think I should switch that to a straight horizontal line and from 3 to 5.6 I drew another upward straight line and finally, for the last 0.4 seconds a straight line on the x axis. For part one and three of the graph, my lines should be straight or curved?
For the other velocity graph, the scan 0007 they asked us to sketch a displacement time graph for that journey. Does my look right?
Thanks,
Peter G
