URGENT Time of sunset using Radius of earth 1. The problem statement, all variables and given/known data 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 170 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. Use the known radius of the Earth to calculate the time t. 2 sig figs 2. Relevant equations 3. The attempt at a solution radius = 6400m radius + height = 6400.015 cos(R/(R + h)) = .54 radians (time/ 1 day) = radians/ 2pi time = ? I dont think im doing this right because im getting like 73000 seconds with this method.
