Solve the following question given below:
Question: Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 5.0m/s. Once free of this area, it speeds up to 13m/s in 8.0 s. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 s to reach a higher cruising speed.
Question 1: What is the final speed?
I need help to determine the final speed and also explain how you got the answer please.
