This document contains code to plot three graphs of velocity (v) over time (t). The first graph models velocity increasing according to an exponential function. The second graph models decreasing velocity with an exponential function. The third graph models increasing then decreasing velocity using two exponential terms and a linear term.

1. t=0:0.00001:0.0005;
v=(1425/119)*(1-exp(-11900*t));
v=v/12;
plot(t,v)
t=0:0.00001:0.0005;
v=(1425/119)*(-1+exp(-11900*t));
v=v/12;
plot(t,v)
t=0:0.00001:0.3;
v=(300*(2.6/1000)*exp(-200.*t)+300*41.2.*t.*exp(-200.*t));
v=v/10;
plot(t,v)
