A train slows down as it rounds a sharp horizontal turn, going from 90.0 km/h to 50.0 km/h in the 16.8 s it takes to round the bend. The radius of the curve is 150 m. Compute the acceleration at the moment the train speed reaches 50.0 km/h. Assume the train continues to slow down at this time at the same rate.(answer in m/s²)
