8. A train has a length of 92 m and starts from rest with a constant acceleration at t = 0. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At t = 14 s, the car reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at a time t = 28 s, the car is again at the rear of the train. Find the magnitude of (a) the car's velocity and (b) the train's acceleration.
