Answer Happy

A car travels down a straight country road that leads over hillsand through valleys. On one particular stretch of road, the carencounters a hill that can be approximated as the top of a circlewith a radius 𝑟h=111 m. Later, the car comes to a dip with a radiusof curvature 𝑟d=83 m. Assume that the car maintains a constantspeed of 𝑣=21 m/s as it goes over the hill and through the dip.
a. The actual weight of the driver, as measured on a flatstretch of road, is 520 N. What is the apparent weight of thedriver at the top of the hill?
b. What is the apparent weight of the driver at the bottom ofthe dip?
