Trimester 2

Unit 7: Collisions

• Homework: Momentum Conservation and Elastic Collisions, both due 2/19

  • Extra Extra Credit: Hardest problem of the year - Consider a solid wall (cannot be moved - any object that collides with it will simply be reflected) fixed to a frictionless floor, and a 1kg block A at rest on that floor. Another block, B, slides towards block A from the side opposite the wall at a speed of 1m/s. It will eventually collide with A, which will collide with the wall, then collide again with B, then again with the wall, and so on. Given that B has a mass of 100^n (also known as 10^2n), there will be exactly FLOOR(pi*10^n) (so, a number represented by the first n+1 digits of pi) collisions before A and B are both moving away from the wall, such that B is moving faster than A. Come up with an explanation for why this would be the case. As a reminder, pi is the circle number, so a circle of some sort will be involved.
