Lab Section: ______ Name: ______________________________ Lab Instructor: ______________________________ Lab Unit # 5 Pre-lab Questions: Collisions I – “Bounce” Collisions 1. (a) In a head-on (1-D) elastic collision between two identical pucks on a frictionless surface, where puck # 1 (“projectile”) is initially moving in the x + direction at speed v towards puck # 2 at rest (“target”), what should be the velocities v and v of the pucks after colliding? 0 x f 1 x f 2 = x f 1 v ____________________. = x f 2 v ____________________. Please include diagrams showing Before and After the collision: Before: After: (b) What should be the velocities of the center of mass (CM) of the two pucks before (i) and after (f) the collision (in terms of v )? 0 = x CMi v ____________________. = x CMf v ____________________. Please show any calculations that you use: (c) Do your answers to part (b) depend on whether or not the collision is elastic ? Please explain briefly. (HINT: Be sure you know what elastic means for collisions.) (Continued on the next page.) P112 Lab Notes Pre-lab 5-1 Cornell University, Fall 2007

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
