A friend of yours was in a car accident when her car skidded off the
road as she rounded a curve. Luckily she survived serious injury,
but she is concerned that the posted speed limit of 35 mph on this section
of road is unsafe. Your friend knows that you are taking a physics
course and decides to get your expert advice. The two of you take
some measurements and determine the radius of curvature of the road to
be about 200 feet, and the road appears to be relatively flat along the
curve (it is not a banked curve). What is your assessment of the
situation?
