A vacuum-propelled capsule for a high-speed tube transportation system of the future is being designed for operation between two stations A and B, which are 12.9 km apart. If the acceleration and deceleration are to have a limiting magnitude of 0.63g and if velocities are to be limited to 440 km/h, determine the minimum time t for the capsule to make the 12.9-km trip. B 12.9 km Answer: t = i min
