Why does toast falling off a table always land jelly-side
Chapter , Problem 26(choose chapter or problem)
Why does toast falling off a table always land jelly-side down? The question may sound silly, but it has been a subject of serious scientific enquiry. The analysis is too complicated to reproduce here, but R. D. Edge and Darryl Steinert showed that a piece of toast, pushed gently over the edge of a table until it tilts off, typically falls off the table when it makes an angle of about with the horizontal (Figure 9-43) and at that instant has an angular speed of where is the length of one edge of the piece of toast (assumed to be square).* Assuming that a piece of toast is jelly-side up, what side will it land on if it falls from a 0.500-m-high table? If it falls from a 1.00-m-high table? Assume that _ _ 10.0 cm. Ignore any forces due to air resistance.
