Why is the following situation impossible? A freight train is lumbering along at a constant speed of 16.0 m/s. Behind the freight train on the same track is a passenger train traveling in the same direction at 40.0 m/s. When the front of the passenger train is 58.5 m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration 23.00 m/s2. Because of the engineer’s action, the trains do not collide.

A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The Ford moves at a constant speed of 30.5 m/s. Just as the Ford passes it, the Toyota is traveling at 15.3 m/s. As soon as the Ford passes the Toyota, the Toyota begins to accelerate forward at a constant rate. Meanwhile the Ford just keeps going at a steady 30.5 m/s to the east. The Toyota catches up to the Ford a distance of 103.8 m ahead of where the Ford first passed it. What was the magnitude of the Toyota s acceleration?     4.5 m/s^2     1.7 m/s^2     8.9 m/s^2     3.4 m/s^2

Please answer all question parts: A Lockheed Martin F-35 Lightning II jet takes off from an aircraft carrier with a runway length of 97 m and a takeoff speed 72 m/s at the end of the runway. Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35's acceleration decreases to a constant acceleration of 4.3 m/s2 at 33° with respect to the horizontal. (Assume that the F-35's initial direction along the deck of the aircraft carrier is the +x-direction and that the +y-direction is up.) (a) What is the initial acceleration (in m/s2) of the F-35 on the deck of the aircraft carrier to make it airborne? (Enter the magnitude.) (b) Write the position (in m) and velocity (in m/s) of the F-35 in unit vector notation from the point it leaves the deck of the aircraft carrier. (Use the following as necessary: t.) (c) At what altitude (in m) is…

A person is driving along a straight highway at a speed of 21.0 m/s when the traffic light which is 43.0 m ahead turns yellow. Because of his reaction time, there's a delay of 0.10s before the man steps on the brakes. The car then slows with a deacceleration of 4.00 m/s^2. By how much distance does the driver miss the traffic light line?
