Challenge the atmospheric pressure at the surface of venus is 91 times the pressure at sea level on earth. with approximately how much total force would venus’s atmosphere push on an average human being at sea level? assume that the surface area of an average human being is 1.8m2

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
