You are traveling on a hilly road. At a particular spot, when your car is perfectly horizontal, the road follows a circular arc of some unknown radius. Your speedometer reads 90.0 km/h, and your apparent weight is 30% larger than usual. Use g-9.80 m/s2 for this problem. (a) Are you at the bottom of a hill or the top of a hill at that instant? the bottom of a hill the top of a hill There's not enough information to...

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 rh = 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...

Problem 3 (30 points) Three cars are driving at 15 m/s along the road shown in Fig 2. Car B is at the bottom of a hill and car C is at the top. Both hills have a 200 m radius of curvature. Suppose each car suddenly brakes hard and starts to skid. a) What is the tangential acceleration (i.e, the acceleration parallel to the road) of each car? Assume μ 1.0. b) What is the centripetal (radial) acceleration of...
