Question
(596) Problem 3: A car drives around the course shown with a constant speed. The course at point A is slightly curved (the radius of curvature ra is large). The radii of curvature rB and rg are equal and the radius of curvature at point D, rp, is the smallest Ip ©theexpertta.com G> Please select the correct ranking for the magnitude of the accelerations experienced. At point C, the road has no curvature Grade Summary Deductions Potential 0% 100% Submissions Attempts remaining:4 (25% per attempt) detailed view Submit Hint I give up! Hints: 3% deduction per hint. Hints remaining: Feedback: 4% deduction per feedback.Explanation / Answer
The acceleration in this course will be v/R2 , v is velocity and R is the radius of curvature.
As R increases, acceleration decreases and as R decreases, acceleration increases.
Specifically, at C, R is infinity and hence acceleration becomes 0.
Hence acceleration rank in ascending order is : C<A<B=E<D (ANSWER is 5th option)
