- Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive. This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg. The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero). Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?A robot pushes a 20-kg giftbox on the horizontal surface as part of the moving job for the holiday season, the force is 27 N to the right as shown.
