Amy gets on a high speed train that is sitting in the station. As it starts to accelerate at a constant rate out of the station, Amy watches a cord with a small mass on the end that is hanging from the ceiling make a 22◦ angle with respect to the vertical. If the train has a constant acceleration for 20s before reaching a constant velocity, what is the speed of the train on her trip (i.e., the velocity reached after 20s of acceleration)?

A train on a straight track starts from rest t station A. It accelerates for 20 seconds with an acceleration of 5 m/s^2 and then continues to travel at the velocity reached for two minutes. The train then decelerates at 5 m/s^2 for 20 seconds before coming to a stop at the next station B. What is the distance between the two stations?
