Don't try this with your parents' dishes

Classical Mechanics Level 2

A cute party trick is to pull a tablecloth out from under a full place setting of dishes, glasses, etc. Consider a stack of plates on top of a tablecloth. If the coefficient of static friction between the plates and the tablecloth is \(0.3\), what acceleration must you give the tablecloth so the plates start to slip? A demonstration of this trick by "Zanthor" is here.

Details and assumptions

  • The acceleration due to gravity is \(9.8~\mbox{m/s}^2\).
  • You pull the tablecloth perfectly horizontally.
