To understand how to find the velocities of objects after a collision. There are two main types of collisions that you will study: perfectly elastic collisions and perfectly inelastic collisions. When two objects collide elastically, both total kinetic energy and total momentum are conserved. These fwo conservation laws allow the final motion of the two objects to be determined. When two objects collide inelastically, total momenjum is conserved, but the tolal kinetic energy is not conserved. After a perfectly inelastic collision, the two objects are stuck together, and thus travel with the same final velocity. This fact, together with conservation of momentum, allows the final motion of the two objects to be calculated. Let two objects of equal mass $m$ collide. Object 1 has initial velocity $v$, directed to the right, and object 2 is initially stationary Now assume that the mass of object 1 is $2m$, while the mass of object 2 remains $m$. If the collision is elastic, what are the final velocities $v_1$ and $v_2$ of objects 1 and 2 ? Give the velocity $v_1$ of object 1 followed by the velocity $v_2$ of object 2, separated by a comma. Express the velocities in terms of $v$. $v_1{v}_2$ * Incorrect; Try Again; 6 attempts remaining
