We will want to be able to calculate velocity from our y vs t data. See the Analysis Help file for an explanation of how to find velocity using the symmetric difference formula.

Using the sample data below, find the velocity v_y at t = 0.566540 s. Note that v_y is negative because the y axis points up.

t(s)	y(cm)
0.549874	35.1630
0.566540	29.9959
0.583206	24.5565

v_y = _________ cm/s
