A 12 m long diesel engine is driven alongside a 400m long freight train with the same velocity of 6 m/s. The front of the diesel engine is 20m behind the rear of the freight train. At a certain instant, the diesel engine starts accelerating at 0.06 m/s^2 while the freight train starts decelerating at 0.3 m/s How long will it take before the rear of the diesel engine passes the front of the freight train?
