40 kg girl skates at 3.5 m/s on ice toward her 65 kg friend who is standing still, with open arms. As they collide and hold each other, what is the speed of the couple?
Answers: 2
![m_{1}*v_{1}+m_{2}*v_{2}=(m_{1}+m_{2})*v_{2}\\(40*3.5)+(65*0)=(65+40)*v_{2}\\v_{2}=140/105\\v_{2}=1.33[m/s]](/tpl/images/0527/9241/21598.png)
