Formative task - conservation of momentum question

A simple task with a Single Point Rubric (SPR) to check understanding of the process of solving a conservation of momentum problem. The task is a standard question that the students must then explain (the question can be easily modified).

These are short tasks, often homeworks, and I usually leave the product up to the student - they just need to meet the criteria.
