Thanks for the reply. Although it is not clear to me how to derive those two equations. - I am a high school physics student and this problem seems more difficult than others I have encountered in the curriculum.

I think you're right - because my answer was slightly off what it was supposed to be. The roadway exerts a normal force n perpendicular to its surface. And the downward force of gravity is present. Those two forces add as vectors to provide a resultant or net force Fnet which points toward the...

Homework Statement A town wants to build a banked curve to join to large roads. The maximum speed they would like cars travel on this curve is 51m/s. The angle of the banked curve is to be 19o and the radius is to be 1.8x102 m. a) What does the coefficient of static friction need to be...
