Two ships are moving along a line due east (see figure below). The trailing vessel has a speed relative to a land-based observation point of
v_(1)=67.0k(m)/(h)
, and the leading ship has a speed of
v_(2)=45.0k(m)/(h)
relative to the point. The two ships are in a region of the ocean where the current is moving uniformly due west at
v_(current )=11.4k(m)/(h)
. The trailing ship transmits a sonar signal at a frequency of
1,200.0Hz
through the water. What frequency is monitored by the leading ship? (Use
1,533(m)/(s)
as the speed of sound in ocean water. Express your answer to five significant figures.)
