A subway train is sitting in a station. It reaches its cruising speed after accelerating at 0.75 m/s2 for distance equivalent to the length of the station (184 m). It then travels at a constant speed
towards the next station 18 blocks away (1425 m).
1. Determine the train's cruising speed.
2. Determine the time it took for the train to accelerate from rest to its cruising speed.
