A train slows down as it rounds a sharp horizontal turn, going from 88.0 km/h to 56.0 km/h in the 13.0 s that it takes to round the bend. The radius of the curve is 160 m. Compute the acceleration (both magnitude and direction) at the moment the train speed reaches 56.0 km/h. [Assume the train continues to slow down at this time at the same rate.]
