When a slice of buttered toast is accidentally pushed over the edge of a counter, it rotates as it falls. suppose the distance to the floor is 89 cm and the toast rotates less than 1 rev. (a) what is the smallest angular speed that causes the toast to hit and then topple to be butter-side down?

Which of the following are guidelines to follow for obtaining accurate observations

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
