Looks a lot like this problem to me. Any feedback for this teacher/ class?

You need a movie camera or other way to break the image into discrete time points to get the reverse motion effect.

The refresh rate of our eyes, or whatever the human version is. Rotations of wheel per second, or seconds per rotation at given speeds. Loads on that little beauty!

Sure it’s possible to “jump” the chasm with no ramp, the far side just needs to be at a slightly lower elevation, provided sufficient speed of the car. But if the car and the spider are going the same speed, why is the spider “more affected” by gravity? I guess the folks at ACME Robot Spiders could answer…
