Object $1$ is moving along the $x$ axis with an initial momentum $+16kg*\frac{m}{s},$ where the $+$ sign indicates that it is moving to the right. As the drawing shows, object $1$ collides with a second object that is initially at rest. The collision is not head$-$on$,$ so the objects move off in different directions after the collision. The net external force acting on the two$-$object system is zero. After the collision, object $1$ has a momentum whose $y$ component is $-5kg*\frac{m}{s}.$ What is the $y$ component of the momentum of object $2$ after the collision?
