A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 37 km/h at the 52-m mark. He then maintains this speed for the next 97 meters before uniformly slowing to a final speed of 31 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur?
