PHYSICSConsider a head-on collision between two objects. Object 1 which has mass $m_{1},$ is initially in motion, and collides head-on with object 2, which has mass $m_{2}$ and is initially at rest. Which of the following statements about the collision are true? $(1)\ \vec{p}_{1, \text { initial }}=\vec{p}_{1, \text { final }}+\vec{p}_{2, \text { final }}.\ (2)\ \left|\vec{p}_{1, \text { final }}\right|<| \vec{p}_{1, \text { initial }}.$ (3) If $m_{2} \gg m_{1},$ then $\left|\Delta \vec{p}_{1}\right|>\left|\Delta \vec{p}_{2}\right|.$ (4) If $m_{1} \gg m_{2},$ then the final speed of object 2 is less than the initial speed of object 1. (5) If $m_{2} \gg m_{1},$ then the final speed of object 1 is greater than the final speed of object 2.
