Two ships are moving along a line due east (Fig. P14.68). The trailing vessel has a speed relative to a landbased observation point of v 1 = 64.0 km/h, and the leading ship has a speed of v2 = 45.0 km/h relative to that point. The two ships are in a region of the ocean where the current is moving uniformly due west at v current = 10.0 km/h. The trailing ship transmits a sonar signal at a frequency of 1 200.0 Hz through the water. What frequency is monitored by the leading ship?
