Question

A student’s results for the first part of 2.2 is a starting point of (t=0.2 s, x=0.6 m) and an ending point of (t=2.7 s, x=1.3 m).

Answer 1

a) What is the velocity? (don’t forget to include units)
b) A second pair of points is (t=0.8 s, x=0.8 m) and (t=2 s, x=1.2 m). What is the velocity
computed from that pair?
c) A third pair is (t=1.2 s, x=0.9 m) and (t=1.8 s, x=1.1 m). Compute the velocity from that pair. d) Compute the average and standard deviation of the three measurements of velocity. It is
convenient but not necessary to use Excel to do this calculation
