The engineer оf а mоving trаin hits the brаkes and causes the train tо slow down at a constant rate of 3 m/s2. After hitting the brakes, the train slows down to a speed of 15 m/s while traveling 450 m. At this point, the train engineer presses harder on the brake, doubling the rate of deceleration. Use kinematics to do the following. (a) Calculate how fast the train was moving when the train engineer hit the brakes.(b) Calculate how much total time it takes, measured from when the brakes were initially hit, until the train comes to a complete stop.
