Write a program named Lab2b. py that takes two observed 3D positions at two points in time, and then calculates the 3D position at a third point in time. Let's consider only times between the two observed times. You should output the x, y, and z values for that position on separate lines. Begin by identifying the variables you will use, the names for those variables, and the computations that should occur for those variables. Then, write a program that will output the 3D position of the interpolated point on 3 separate lines.
