Chapter 6, Problem 6CQ
Pace car drivers routinely cut corners as shown in Figure 6.32. Explain how this allows the curve to be taken at the greatest speed.
Figure 6.32 Two paths around a race track curve are shown. Race car drivers will take the inside path (called cutting the corner) whenever possible because it allows them to take the curve at the highest speed.

In elementary school, there was a very large hill right next to the school. My mom would always try to drive so fast up the hill that we would fly off the road. I can’t actually remember if she did, or if she just created such magic aroudn driving fast that it felt like we did. Let’s estimate that the hill had a curved top with a radius of 35 meters. How fast would she have to drive (in mph) to fly off the road?
You're designing a highway so that the maximum centripetal acceleration on a curve is no more than 1.7 m/s2. What is the minimum curvature radius to accommodate a 52-km/h maximum speed? Give your answer in meters
I know the formula involves a= v^2/r and we get r by itself; and then, we are to find minimum curvature radius. My question has to do with a conversion of 52 km to meters, and yes, km=1000 m. Can you help me to conceptualize (52 km/h)^2 to (14.4 m/s)^2 better?
Hello,
Can someone please show how to solve this problem?
Thanks
