Two carts of unequal mass are sent into a collision.  The velocities of each cart both before and after are found so that the total momentum before and after the collision can be determined and compared. This is the Lab 3 Tier 2 Challenge Set-Up. This set-up presents an “error” in conducting the trial which affects the student’s result. The challenge is for the student to determine what Danny did wrong in conducting his trial and determining how the error impacted the results.
