A train has a length of 92m and starts from rest with a constant acceleration at a time 0secs. At this instant, a car just reaches the end of the frain. The car is moving with a constant velocity. At a time t = 14 secs, the car just reaches the front of the frain. Ultimately, however, the train pulls ahead of the car, and at time t = 28secs, the car is again at the rear of the train.

Find the magnitudes of (a) the car's velocity, (b) the train's velocity at t = 28 secs, and (c) the train's acceleration.
