A truck with a mass of 1530 kg and moving with a speed of 13.0 m/s rear-ends a 733 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second.

![m_{A}= 1530[kg]\\v_{A}= 13[m/s]\\m_{B}=733[kg]\\v_{B}=0\\](/tpl/images/0561/1526/727b4.png)
![m_{A}*v_{A}+m_{B}*v_{B}=(m_{A}+m_{B})*v_{2}\\replacing:\\(1530*13)+(733*0)=(1530+733)*v_{2}\\v_{2}= 8.79[m/s]](/tpl/images/0561/1526/97b94.png)
