P40. A train slews down as it rounds a sharp horizontal turn, going from 90.0 km/hr to 50.0 km/hr in the 15.0 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/hr. Assume the train continues to slow down at this time at the same rate.
