**the answer**(as a way to check our answers) :

__1.48 m/s^2 inward and 29.9 degrees backward__

__The problem is__: 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.

Thank you in advance for helping me!
