A train slows down as it rounds a sharp horizontal turn, going from 82.0 km/h to 46.0 km/h in the 12.0 s that it takes to round the bend. The radius of the curve is 170 m. Compute the acceleration at the moment the train speed reaches 46.0 km/h. Assume the train continues to slow down at this time at the same rate. m/s² magnitude direction backward (behind the radial line pointing inward)
