(III) Another experiment you can do also uses the radius of the Earth. The Sun sets, fully disappearing over the horizon as you lie on the beach, your eyes 20 cm above the sand. You immediately jump up, your eyes now 150 cm above the sand, and you can again see the top of the Sun. If you count the number of seconds (= t ) until the Sun fully disappears again, you can estimate the radius of the Earth. But for this Problem, use the known radius of the Earth and calculate the time t.

There are 2.54 cm per inch. 3.1 cm is the same distance as
A surveyor measures the distance across a straight river by thefollowing method: starting directly across from a tree on theopposite bank, he walks x = 1.00 x 102 m along the riverbankto establish a baseline. Then he sights across to the tree. Theangle from his baseline to the tree is θ = 35.0° (Fig. P1.53).How wide is the river?
