PLEASE ANSWER dont answer if you dont know Think about what forces are involved in the different parts of this investigation. Explain why there is a difference in the amount of Newtons measured when you weighed the objects versus when you pulled the objects across a surface. Your answer should mention how the force=mass*acceleration formula is involved.

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
