Submitted by Dave Thomas
Derive the approximation for the distance d to the horizon for an object at height h above the earth, d ~ √2hR, where R = radius of Earth (~ 3960 miles), and also for the angle of dip of the horizon, d/R*180/π in degrees.
The October Bonus:Assuming Mt. Wahdoo-ainoh is five miles above the surrounding terrain, what is the distance to the horizon from its summit? And the Dip Angle of the horizon?
