The magnitude of the maximum acceleration is typically 1.3 {rm m}/{rm s}^{2}, but the driver will usually maintain a constant acceleration that is less than the maximum. A train travels through a congested part of town at 6.0 m/s. Once free of this area, it speeds up to 11 m/s in 8.0 {rm s}. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 {rm s} to reach a higher cruising speed. What is the final speed?
