A train slows down as it rounds a sharp horizontal turn, slowing from 90.0 km/h to 50.0 km/h in the 15.0 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 50.0 km/h. Assume it continues to slow down at this time at the same rate.(adsbygoogle = window.adsbygoogle || []).push({});

So ifat=d|v| /dt, what is the function to evaluate? I think calculus fell out of my head over the summer. Thanks for your time.
