Banked Curves: A curved portion of highway has a radius of curvature of 65 m. As a highway engineer, you want to bank this curve at the proper angle for a steady speed of 22 m/s.(a) What banking angle should you specify for this curve?(b) At the proper banking angle, what normal force and what friction force does the highway exert on a 750-kg car going around the curve at the proper speed?
What will be an ideal response?
(a) 37° (b) 9200 N (normal force), 0 N (friction)
