A train has a length of 98.0m and starts from rest by a constant acceleration at time t=0s. At this instant, a car just reaches the end of the train. The car is moving by a constant velocity. At a time t=12.0s, the car just reaches the front of the train. Ultimately, but, the train pulls ahead of the car, and at time t=27.0s, the car is again at the rest of the train.
1) Discover the magnitude of the cars velocity ____m/s
2) Discover the magnitude of the train's acceleration. ______m/s^2
