Need some exercise for your neurons? Read on....
As I was sitting in my stationary Motorhome, contemplating life on a beautiful, bright but partially cloudy day, my eyes wandered towards the windshield. In front of the RV I had parked my Minivan at a right angle to the RV.
I noticed the reflection of beautiful whisper clouds racing across the essentially flat side window of the van. I asked myself: wonder at what speed the clouds are moving from West to East. Many thoughts went through my mind for calculating the speed. I gave up after I felt my neurons getting tangled up. Good question for all the sharp folks here on the forum, I thought.
Anyone wish to tackle this problems? Here are the parameters that may play a role.
1. The window is 4 feet (1.2 m) in length.
2. The angle from vertical about 20 ?
3. Est. altitude of the clouds about 2000 feet (670 m)
4. Time for the edge of a cloud to move across the window in straight line, left to right, 60 seconds (1 minute)
(Cloud formation virtually unchanged during this interval)
What is the speed of the clouds? Would that be the wind speed as well?
Call this a trivia question; I don't think this will solve anything except maybe give you a headache.
