Use x= x0cos2π t to produce a table o values o x and t or values:

t/s = 0, 0.04, 0.08, 0.12, 0.16, 0.20, 0.24, 0.28, 0.32, 0.36

t/s	x/m
0	0
0.04	0.03051
0.08	0.00653
0.12	-0.02054
0.16	-0.03787
0.2	-0.03722
0.24	-0.0189
0.28	0.00838
0.32	0.03169
0.36	0.03996

Draw a graph on the attached graph paper of x against t and use it to find the maximum speed at the end of the ruler.
