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 car weighing 2.5 metric tons and traveling at 90 km/h hits a 500 m long stretch of black ice. Unfortunately, due to skidding, neither accelerating nor braking has any effect on the speed! The driver manages to maintain steady straight direction of motion and the only impact is provided by the ice friction force, which is numerically equal to 4v² Newtons, where the velocity v of the car is measured in m/sec. (a) Using Newton's Second Law F = ma, set up a mathematical model for the position x(t) and velocity v(t) of the car as functions of time t. Start by drawing a diagram and choosing a consistent system of units based on kg, m, sec (1 ton = 1000 kg, 1 m/sec = 3.6 km/h, 1 N = 1 kg · m/sec²). Introduce and label the variables, show the units and write down the differential equations and the intial conditions. (b) Use the model in part a to calculate v(t) and x(t). Fully show the process of solving the initial value problems. (c) Based on your work so far, how long will it take to pass…
