A train slows down as it rounds a sharp horizontal turn slowing from 90.0km/h to 50.0km/h in the 15.0s that it takes to round the bend. The radius of the curve is 150m. Compute the acceleration at the moment the train reaches 50.0km/her. Assume it continues to slow down at this rate.
Vf = Vi + a*t
Ac = V2 / r

I am totally confused and have to hand in this problem tomorrow and I don't have the text book to reference.
