A Curved Portion of Highway Has a Radius of Curvature

question 94

Short Answer

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?

Definitions:

Achiral

Describing a molecule that is superimposable on its mirror image, thus not exhibiting chirality.

Chiral

Describes a molecule that cannot be superimposed on its mirror image, often leading to different reactions and interactions depending on the spatial arrangement of its atoms.

Enantiomer

A molecule from a duo that resembles its counterpart as a mirror reflection but cannot be perfectly overlaid, similar to the relationship between the left and right hands.

Achiral Molecule

A molecule that is superimposable on its mirror image, lacking chirality or a distinct handedness.
