Animate Marbles
Problem Statement:
The pre-placed blocks animate the red marble rolling to the blue marble. After they collide, the red marble is still and the blue marble rolls forward at the same speed the red marble was moving. After it rolls over the ledge, the blue marble falls with a parabolic arc. Add more blocks to create this animation.
