A person driving at 17 m/s crosses the line connecting two radio transmitters at right angles, as shown in Figure 28-41 The transmitters emit identical signals in phase with each other, which the driver receives on the car radio. When the car is at point A. the radio picks up a maximum net signal. (a) What is the longest possible wavelength of the radio waves? (b) At what time after the car passes point A does the radio experience a minimum in the net signal? Assume that the wavelength has the value found in part (a).

In a naval battle, a battleship is attempting to fire on a destroyer. The battleship is a distance
d1 = 2,150 m
to the east of the peak of a mountain on an island, as shown in the figure below. The destroyer is attempting to evade cannon shells fired from the battleship by hiding on the west side of the island. The initial speed of the shells that the battleship fires is
vi = 245 m/s.
The peak of the mountain is
h = 1,840 m
above sea level, and the western shore of the island is a horizontal distance
d2 = 250 m
from the peak. What are the distances (in m), as measured from the western shore of the island, at which the destroyer will be safe from fire from the battleship? (Note the figure is not to scale. You may assume that the height and width of the destroyer are small compared to d1 and h.)
