Suppose a car travelling at 12 m/s, sees a traffic light turn red. After 0.510s have elapsed, the driver applies the brakes, and the car decelerates at 6.2 m/s2. What is the stopping distance of the car as measured from the point where the driver first notices the red light?

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
