O Macmillan Learning A car travels down a straight country road that leads over hills and through valleys. On one particular stretch of road, the car encounters a hill that can be approximated as the top of a circle with a radius r = 105 m. Later, the car comes to a dip with a radius of curvature rd = 75 m. Assume that the car maintains a constant speed of v = 23 m/s as it goes over the hill and through the dip. Figure not to scale. The actual weight of the driver, as measured on a flat stretch of road, is 770 N. What is the apparent weight W₁ of the driver at the top of the hill? What is the apparent weight Wɖ of the driver at the bottom of the dip? N Wh =
