(25 pts.) The 1.8 Mg dragster is traveling at 125 m/s when the engine is shut off and a parachute is deployed. If the drag force can be modeled based on the graph, determine the speed of the dragster after it has traveled 400 meters. Use the work energy theorem to solve the problem. . 50 20- s (m) 400

    Pictured below is a model for a train that is traveling at the steady speed of 50 m/s through standard air at sea level. The cross section of the train will be modeled as a semicircle so that the train itself is half of a circular cylinder. Neglect the effects of any airflow beneath the train. The engine car drives the train with a propulsive thrust, and there is a coupling connecting the engine car to the passenger car. Assume...
