Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_130

5/130 If the cars of Prob. 5/129 both have a constant speed of 72 km/h as they round the curves, determine the acceleration which A appears to have to an observer riding in and turning with car B for the instant represented. Axes x-y are attached to car B. (From Prob. 5/129): Cars A and B are rounding the curves with equal speeds of 72 km/h. Determine the velocity which A appears to have to an observer riding in and turning with car B for the instant represented. Does the curvature of the road for car A affect the result? Axes x-y are attached to car B. [The diagram shows car B moving in the \(+y\) direction on a curve of radius 100 m, and car A moving in the \(-y\) direction on a curve of radius 100 m. The distance between them is 30 m.]
