Question:
You are laying on the grass with your partner, staring up at the sky as a plane sky-writes letters above (you have arranged a romantic message). Both of you have normal vision. You know that the plane is 3 km above you, and you can assume the letters are taking up approximately 5 arc-minutes of your vision since they are distinguishable. A. Given this data, determine the height of the letters in meters. B. The wind picks up and begins scrunching up the letters at a rate of 10ft/minute. For how long will the sky writing be visible?
