Chapter 11, Problem 51(choose chapter or problem)
Catching a Train Bills train leaves at 8:06 AM and accelerates at the rate of 2 meters per second per second. Bill, who can run 5 meters per second, arrives at the train station 5 seconds after the train has left and runs for the train. (a) Find parametric equations that model the motions of the train and Bill as a function of time. [Hint: The position s at time t of an object having acceleration a is ] (b) Determine algebraically whether Bill will catch the train. If so, when? (c) Simulate the motion of the train and Bill by simultaneously graphing the equations found in part (a).
