Suppose that a highway exit ramp is designed to be a circular segment of radius p = 175 ft. A car begins to exit the highway at A while traveling at a speed of 65 mph and goes by point B with a speed of 25 mph. Compute the acceleration vector of the car as a function of the arc length s, assuming that between A and B the speed was controlled so as to maintain constant the rate dvi ds. (Round the final answers to four decimal places. Include a minus sign if necessary.) A B The acceleration vector of the car is a =(([ 1.5-2)5²) Un- ft/s2) + ] 5-2)s) ût + (([ ] ft/s²)-([]s-²) + ft-
