Answer to Question #3437 in Mechanics | Relativity for Demi Deryn
The empire state building, 380 m high is observed by a man 3.567 km away. What is the angle between the ground and his line of sight to the top of the building?
The distance in meters from the building is 3567 m away. The Empire state building, the disance, and the line connecting the man and the top of the building make together the right triangle. & tan (α) = 380/3567 = 0.1065 hence α = 6.1 degree.
