Apenguin slides at a constant velocity of 1.43 m/s down an icy incline. the incline slopes above the horizontal at an angle of 6.47°. at the bottom of the incline, the penguin slides onto a horizontal patch of ice. the coefficient of kinetic friction between the penguin and the ice is the same for the incline as for the horizontal patch. how much time is required for the penguin to slide to a halt after entering the horizontal patch of ice?

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
