Homework Statement
A) 3000 pound car is negotiating a circular interchange or radius 300ft at 30mph. Assuming the road is level, find the force between the tires and the road such that the car stays on the circular path without skidding.
B) Next, Find the angle at which the roadway should be banked so that no lateral force is exerted on the tires of the automobile.
Homework Equations
F = ma
m = 3000/32
tanθ = v^2 / rg
θ = tan-1(v^2 / rg ) .
v = velocity of the vehicle = 30
r = radius of banking = 300
g = accleration due top gravity
The Attempt at a Solution
I really don't know - this is a question from a calculus course and is one of the more challenging problems at the chapter's end. Having never taken even introductory physics, if anyone could help me out with the calculations + brief explanation that would be wonderful.
