1) Some civil engineers are designing an Autobahn connecting Reno and Vegas to reduce the drive time. There are several hilly stretches between the two cities. They would like to keep the magnitude of acceleration on the drivers to be less than one g. They run a test where the speed of a biker decreased uniformly with time from 150 km/h at A to 100 km/h at B over 10 seconds. The radius of curvature for dip A is 200 m. If the magnitude of the total acceleration of the center of the mass of the bike is the same at B as at A, compute the radius of curvature rs of the hill in the road at B. The center of the mass of the car is 0.5 m from the road. [Ans. To Check: rB=88.5m] TA = 200 m A VA= 150 km/h H = 0.5 m B VB = 100 km/h TB = ? m

7. You can swing a ball on a string in a vertical circle if you swing it fast enough. But if you swing too slowly, the string goes slack as the ball nears the top. Explain why there's a minimum speed to keep the ball moving in a circle. 8. A curve in a road has a bank angle calculated and posted for 80 km/h. However, the road is covered with ice, so you cautiously plan to drive slower than this limit. What might happen to your car? Why? 9. Why do airplanes bank when they turn? How would you compute the banking angle given the airspeed and radius of the turn? [Hint: Assume an aerodynamic "lift" force acts perpendicular to the wings].

A human-powered vehicle (HPV) team wants to model the acceleration during the 260-m sprint race (the first 60 m is called a flying start) using a= A- Cv2, where a is acceleration in m/s2 and v is the velocity in m/s. From wind tunnel testing, they found that C = 0.0012 m-1 . Knowing that the cyclist is going 100 km/h at the 260-meter mark, what is the value of A?
