A railroad bumper is designed to slow down a rapidly moving railroad car. After a 20,000 kg railroad car traveling at 20 m/s engages the bumper, its displacement x (in meters) and velocity v (in m/s) as a function of time t (in seconds) is given by:
x(t) = 4.219(e-1.581 - e-6·321) and v(t) = 26.67e-6.321 - 6.67e-1.5Bt
Plot the displacement and the velocity as a function of time for 0 < t < 4 s. Make two plots on one page.
