(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A train slows down as it rounds a sharp horizontal turn slowing from 90.0 km/h to 50.0km/h in the 15 s that it takes to round the bend. The radius of the curve is 150 m. Compute the acceleration at the moment the train speed reaches 50km/h. Assume it continues to slow down at this time at the same rate.

2. Relevant equations

3. The attempt at a solution

I think this problem is asking to find the instantaneous velocity at t = 15 sec, which when the speed of the train is 15 sec. From the above information give, we can find the acceleration of the train during from 90-50, which is 11.55 using the formula Vf = Vot + 1/2at^2. Then I am stuck here
