Compute the acceleration at the moment the train speed

Reference no: EM13715181

Question: A train slows down as it rounds a sharp horizontal turn, going from 84.0 km/h to 40.0 km/h in the 13.0 s that it takes to round the bend. The radius of the curve is 120 m.

Part A: Compute the acceleration at the moment the train speed reaches 40.0 km/h.

I need tutor help to solve the above question and assume the train continues to slow down at this time at the same rate.
