When you cough, your windpipe contracts. The speed, v, with which air comes out depends on the radius, r, of your windpipe. If R is the normal (at rest) radius of your windpipe, then for r<_(less than or equal to)R, the speed is given by: v=a(Rr)r^(2), where a is positive constant. What value of r maximizes the speed?
