A train departs Station A to travel to Station B which is 1369 meters away. The train begins at rest and accelerates at a rate of 1.36 m/s2 until it reaches a speed of 20.0 m/s. As the train approaches station B, it begins to decelerate at a rate of 0.62 m/s2 so that it comes to a complete stop just as it arrives at Station B. Determine the average velocity of the train over the entire trip.

    begins A commuter train traveling at 45MPH is ómiles from the station. The train to decelerate so that its speed is 15MPH when it is 0.5miles from the station. Knowing that the train arrives at the station 14minutes after beginning to decelerate and assuming constant deceleration, find : a) time required for the train to travel the first 5.5 miles, b) the final deceleration of the train, c) the speed of the train as it arrives at the station.

    Joe wakes up to find himself tied to the train tracks. He sees a train 450 meters away, moving towards him at a speed of 42 m/s. At that moment, the train operator sees Joe and engages the brakes, causing it to decelerate at a rate of 1.4 m/s^2. Joe knows the train will not stop before it reaches him. How much time does Joe have to free himself and escape a grisly death?

    In the design of a rapid transit system, it is necessary to balance the average speed of a train against the distance between stops. The more stops there are, the slower the train's average speed. To get an idea of this problem, calculate the time it takes a train to make a 7.0 km trip in two situations. (Assume that at each station the train accelerates at a rate of 1.1 m/s2 until it reaches 95 km/h , then stays...

    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?

  • A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s

    A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s. It runs at a constant speed for 50.0 s and slows down at a rate of 3.20 m/s2 until it stops at the next station.
