A train has a length of 93.8 m and starts from rest with a constant acceleration at time t-Os. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t- 16.0s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 36.0 s, the car is again at the rear of the train. Find the magnitudes of (a) the car's velocity and (b) the train's acceleration. (a) Number i (b) Number Units Units

A train has a length of 93.8 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 = 16.0s, the car just reaches the front of the train. Ultimately,
however, the train pulls ahead of the car, and at time t = 36.0 s, the car is again at the rear of the train. Find the magnitudes of (a) the
car's velocity and (b) the train's acceleration.
