On a level road the stopping distance for a certain car traveling at 80 km/hr is 32 m. what would be the stopping distance for a car when going down a hill on a 1 : 10 grade? (A grade of 1 : 10 means the elevation drops 1 m for a forward travel of 10 m along the roadway.)

In a system, when potential energy decreases, then entropy also decreases. true false

What occurs during a combustion reaction

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
