A 130-KG tackler moving at 2.5 m/s meets head on(and tackles) a 90 k-g halfback moving at 5.0 m/s. What will be their mutual speed immediatley after the collison?
someone please check my work
[tex]m_{1}v_{1}+m_{2}v_{2}=v'(m_{1}+m_{2})[/tex]
so [tex]v'=\frac{325+450}{220}[/tex]
[tex]v'=3.52 m/s[/tex]
