In the figure below the y-axis points north, the z-axis points east, and the zy-plane corresponds to the surface of the water. Suppose a boat is at point B, a submarine is 8 units below point S, and a helicopter is 15 units above point H. 1. Find the displacement vector and the distance from the submarine to the boat. Displacement: O Distance: [j 2. Find the displacement vector and distance from the helicopter to the boat. Displacement: D Distance: D 3. Find the displacement vector and distance from the submarine to the helicopter. Displacement: E] Distance: E] Find the following expressions using the graph below of vectors u, v, and w. y u
