A train slows down as it rounds a sharp horizontal turn, slowing from 53.4m/s to 22.0m/s in the 19.2s that it takes to round the bend. The radius of the curve is 203.6m. Compute the magnitude of the total acceleration at the moment the train speed reaches 33.8m/s. Assume that it slows down at constant rate. Give your answer with two decimal places in m/s².
