A train has a length of 104 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 8.14 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 39.9 s, the car is again at the...

A train has a length of 107 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 11.3 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 37.3 s, the car is again at the...
