Chapter 1, Problem 34P(choose chapter or problem)
(III) Many sailboats are docked at a marina 4.4 km away on the opposite side of a lake. You stare at one of the sailboats because, when you are lying flat at the water’s edge, you can just see its deck but none of the side of the sailboat. You then go to that sailboat on the other side of the lake and measure that the deck is 1.5 m above the level of the water. Using Fig. 1–16, where \(h=1.5 \mathrm{\ m}\), estimate the radius of the Earth.
FIGURE 1-16 Problem 34. You see a sailboat across a lake (not to scale). is the radius of the Earth. Because of the curvature of the Earth, the water “bulges out” between you and the boat.
