SECTION B

Graphing activity.

Complete the graph on paper and hand in to Mrs Kühn at the end of the session.

Collect graph paper (or use your own) before you start this task. This graph MUST be handed in at the end of the E-day session in order for it to be marked.

To type answers that have superscripts, please follow this format (using ^ to indicate superscript):

For scientific notation: e.g. One hundred thousand (100 000) would be typed like this: 1,0 x 10^5

For units such as metres per second squared, type is like this m.s^-2
