4- (15 points) Two cars are driving on I-40 towards Phoenix. Car A is traveling at a speed of 70 mi/h while car B is going slower at 50 mi/h. Car A maintains a constant speed throughout the travel while car B increases speed by 1100 mi/h2. At the instant shown in the picture: A Determine ONLY the acceleration of Car B with respect to Car A (aB/A). Car B moves along a curve with a radius of curvature of PB = 0.7 mi. 30° Hint: Find all components on x-y coordinates and use vector analysis. Extra Credit (2 points) Find the direction of aB/A with the horizontal axis. 50 sin(600) = 25 VA = 70 mi/h- B a=110 VB = 50 mi/h 0.7m
