Suppose a postman is trying to escape from a dog chasing him. The postman starts at the origin and runs away in a straight line at a constant speed v. Meanwhile, the dog starts at a point somewhere off that line and runs with constant speed w, instantaneously swerving in such a way that it is always heading straight toward the postman's current location. Find the equation for the curve traced out by the dog. Find this curve y(x) dog speed w ·▲ speedy man
