The question is:
A train slows down as it rounds a sharp horizontal turn,slowingfrom 90.0 km/hr to 50.0 km/hr in the 15.0 s that it takes toroundthe bend. The radius of the curve is 150.0 m. Computetheacceleration at the moment the train speed reaches 50.0km/hr.Assume it continues to slow down at the same rate.
I'm just not sure how to set up this problem, just a hint willdo.Thanks!
