End Question:

Here we see four possible paths, A, B, C, and D. What’s your take on this? When the marble rolls off the edge, will it follow path A — directly outward from the rotating record? Will it follow a curve, something like that of path B? Will it follow a straight line as shown in C? Or will it follow a tangent line as shown in D?
