Like the staff version on Facebook too! It's called "NYLT Staff"
You don't have to be a staff member to join, you just have to appreciate the staff of NYLT course and the volunteer work staff puts in!

The disadvantage of being left-handed. It's almost like a bit of suspense waiting for the hand to move out of the way so you can read it.

11 people so far do not agree with you. Instead of bashing others' things they post, just keep scrolling down past it if you don't like it

Hey guys, spread the news of NYLT! Summer is coming around and registration is needed for the NYLT courses! NYLT almost always suffers a little the year of Jambo (last year), so those numbers need to be brought back up! Spread the news of the course and this page!

DETAILS OF THE FALL-

   The iPad fell from about 100,000 or 30500m (meters). This definitely gives it enough time and distance to reach terminal velocity. 

   The iPad surface area is 44,790mm squared. We will add some because of the mounting bracket and the camera and all of that. So we will make it 50,000mm squared.

   The acceleration of Gravity is  9.80665 m/s/s (or meters per second squared). Using [v=sqrt{2gd}], it's speed in m/s (meters per second) is 773.438. Now this doesn't take surface area into account. Because this gives us a speed of about 1730mph. That is over mach 2 and is outrageous. So we will disregard this calculation entirely. 

   Drag coefficient is calculated by the shape of the object. The object a rectangular prism, but the bag it is in provides some angles. So does the cylindrical mounting bracket. And the camera is kind of a square, so the average drag coeffient of all three of these shapes (and we will add a bit to compensate for the popped balloon) comes out to be about 1.5.

   Vterminal=sqrt{(2*mass*gravity)/(density of air*projected area*drag coefficient)}

   Average air density~ 1.3 kg/m cubed
   Mass= .73 kg
   Drag Coefficient~ 1.5
   Projected area= 50000mm squared
   Accel due to gravity= 9.80665m/s/s

   The answer comes out to be 10.2417 m/s. When converted  into mph, it equates to a speed of 27.11mph. Looking at the footage, that seems about right.

How many of you guys are a staff member at an NYLT course? I am

+Dalton Laperriere Sweet! I love your council's 2010 Jamboree patch set! I traded for your council's "BSA STAFF" set at Jambo.
