Object A has mass $m_A=9kg$ and initial momentum $,$ just before it strikes object B $,$ which has mass $m_B=11$ kg $.$ Just before the collision object B has initial momentum vec

Part $1$

Part $2$

Your answer is partially correct.

The forces that A and $B$ exert on each other are very large but last for a very short time. If we choose a time interval from just before to just after the collision, what is the approximate value of the impulse applied to the two$-$object system due to forces exerted on the system by objects outside the system?
