Noah is loading the ark and the last animal on board is a stubborn 1500-kg elephant who refuses to budge. noah and his family pull the elephant at a constant speed up the 10° incline with a force of 10,000 n. what is the coefficient of sliding friction between the elephant and the loading platform?

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
