Amover uses a ramp to pull a 1000 newton caart up to the floor of his truck (0.8 meters high). if it takes a force of 200 newtons to pull the cart what is the length of the ramp. for 50 points

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
