Показать описание
This is the video that cover the section 5.O in the AP Physics 1 Workbook.
Topic over:
1. How mass doesn’t affect total mechanical energy of the system
2. How mass does affect total momentum of the system
3. Deriving an equation to solve for the velocity of an inelastic collision.

This is a packet given to student by the CollegeBoard and for student to do. Students are to give the packet an honesty attempt and effort. This video is created to supplement the learning and to provide assistance to student in the learning process and is not supposed to be use as a cheating tool.

i dont understand your anwser to question II. the way i see it the spring is applying a set impulce into the car at the start. this means that the momentum is set at all times, and that any increase of mass must be matched by a lowering of the velocity. the momentum should stay the same

You rationalized wrong, M is not supposed to be squared in the last equation
