Ray's challenge

Don't know how many of you saw this today...or how many of you care. BUT, here is today's photo and post from Ray's weather center...any takers?

We have not had a contest in ages, and I'm fearful of the amount of email I'm about to receive... but here we go. Students think that college professors just sit around all day thinking of mean things to assign; well, sometimes that's correct. In our faculty lounge Monday (Computer Science Dept. at ASU) Dr. Rahman Tashakkori (Dr. Jay Fenwick was chiming in too with this evil plot) and I decided that it was not good that students were out of school missing all the education they would have received otherwise. So the three of us decided you needed make-up homework.
Here's the challenge...

Below is a photo of the snow taken at Dr. Tashakkori's house Sunday February 12. There was about 4" of snow on the trampoline at the time. He wondered if the weight of the snow was over the advertised 250 lb weight limit for the trampoline. The trampoline is slightly over 14' in diameter. Your assignment is to answer two questions: 1) What is the weight of the snow on the trampoline? and Exactly when (time of day) was the photo taken?
Send your answers to ray@raysweather.com with the word "Contest" in the subject field. In the text of the email, put only the following information (in this order, each item on a seperate line):

• Your name
• Your email address
• Your estimate of the snow's weight
• Your estimate of the time of day

Don't send me email asking for more information--college professors are mean like that. I'll give a T-shirt to the persons who have the most accurate estimates. Children of ALL ages are eligible to win (even if you did not have to miss school Monday, you can call this "extra credit").

Yes, Dr. Tashakkori sampled the snow, melted it, weighed the water, and calculated the weight of the snow. College professors are like that sometimes! Many thanks to him for providing the problem.

Now, what are doing reading this... Go calculate!
