1. The problem statement, all variables and given/known data
A bug slides back and forth in a bowl 11 cm ddep, starting from rest at the top. The bowl is frictionless except for a 1.5 cm wide sticky patch on its flat bottom, where the coefficient of frictino is .61. How many times does the bug cross the sticky region???
Anybody have any ideas. I can't find an equation that uses the coefficient of friction and potential energy...
