Question:

Consider the freight train in Figure 16.6. Suppose that 15 boxcars pass by in a time of 12.0 s and each has a length of 14.0 m.

(a) What is the frequency at which each boxcar passes?

(b) What is the speed of the train?

Figure 16.6:

The time for one car to pass is the period T Velocity = v Wavelength = A-
