If you did not have access to a microscope on your next investigation to determine the living or nonliving nature of a sample, what might you do?

A car is 2.0 km west of a traffic light at t = 0 and 5.0 km east of the light at t = 6.0 min. Assume the origin of the coordinate system is the light and the positive x direction is eastward.

For each of the following, draw the resulting wave when the two pulses occupy the same space. Unless otherwise noted, each wave has an amplitude of + / - A.
