Name, sanathon Toietsch Physics 2010 Passage 4: Megawoosh versus LabRecit Day: w Th Fr Waterslide Wipeout Lab/Recit Time a 12p 2p 4p TA Name: In 2009, a German subsidiary of Microsoft created a video of a man sliding down a huge waterslide in the Alps, flying through the air, and landing safely in a child's swimming pool: help www.youtube com watch?veb response The video is a clever fake! See http://gigaom.com/video the megawoosh waterslide viral-howit was really done! Not to be outdone in the debunking department, the Mythbusters tested whether such a stunt could have been done. In the episode "Waterslide Wipeout" they tested both the accuracy and distance of such a jump in inimitable Mythbusters style by building a full-scale copy of the Megawoosh waterslide and testing it by sliding down it themselves. Let's investigate this jump! We will assume that friction along the side is zero and air resistance is zero. At the end of the assignment you will determine whether the Megawoosh stunt is theoretically consistent with Newton's laws as long as friction and air resistance are neglected. and air resistance were present in all their glory) Adam Savage measured the dimensions of the ramp from the video and constructed the following: FEET ELENGTH FEET SLOPE ANGLE 24 Let's translate to SI units and use the following schematic figure (next page, not drawn to scale)as an approximation.

Explanation / Answer

6] Using third equation of motion,

v^2 = 0^2 + 2aL3

v = sqrt(2aL3)

option E is correct
