Acar with s mass of 2000 kilograms is moving around a circular curve at a uniform velocity of 25 meters per second. the curve has a radius of 80 metered. what is the centripetal force on the car

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
