A train normally travels at a uniform speed of `72 km//h` on a long stretch of straight level track. On a particular day, the train was forced to make a `2.0` minute stop at a station along this track. If the train decelerates at a uniform rate of `1.0 m//s^2` and accelerates at a rate of `0.50 m//s^2`, how much time is lost in stopping at the station ?
