Two blocks, which have masses 
and 
, slide along a frictionless, semi-infinite track bounded by a stationary wall. Initially block 2 is not moving, and block 1 moves to the left with speed 
. All of the collisions are elastic.
and , slide along a frictionless, semi-infinite track bounded by a stationary wall. Initially block 2 is not moving, and block 1 moves to the left with speed . All of the collisions are elastic. Write a function to count the collisions between the two blocks and block 2 and the wall. For example, if the blocks each have mass of 1 kg and block 1 initially moves to the left at 0.5 m/s, there will be three collisions: the initial collision, a collision between block 2 and the wall, and a final collision between the blocks.

Chris, I was just thinking of posting this problem, after something popped up in my social media feed awhile ago. But you beat me to it haha!
I bet I know what you saw! It was fascinating.
It was!
Fascinating, indeed --- and I should thank you both for the pointer, since without this problem and your preceding comments, I wouldn't have seen that "something"!
