Water has a density of 1.0 g/cm3. glycerin, a liquid used in some soaps, has a density of 1.26 g/cm3. if an object sinks in water but floats at a constant depth in glycerin, its density is 1.) exactly 1.26 g/cm3 2.) greater than 1.26 cm3 3.) between 1.0 g/cm3 and 1.26 cm3 4.) less than 1.0 g/cm3

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
