Answer:
v2 = 8.79 [m/s]
Explanation:
It is assumed that both vehicles are attached after impact, therefore it is perfectly elastic.
We will use the following initial data:
[tex]m_{A}= 1530[kg]\\v_{A}= 13[m/s]\\m_{B}=733[kg]\\v_{B}=0\\[/tex]
We need to find the final speed after the collision.
[tex]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][/tex]
