Standing still, Bruce, the quarterback, gets tackled by Biff, the 90.0-kg tackle, who is traveling at 7.0 m/s. Upon collision, Biff stops and Bruce goes flying off at 10 m/s. What is Bruce's Mass?​

Answer :

[tex]\\ \sf\longmapsto \Delta P=P[/tex]

[tex]\\ \sf\longmapsto m1v1=m2v2[/tex]

[tex]\\ \sf\longmapsto 90(7)=m2(10)[/tex]

[tex]\\ \sf\longmapsto 10m2=630[/tex]

[tex]\\ \sf\longmapsto m2=\dfrac{630}{10}[/tex]

[tex]\\ \sf\longmapsto m2=63kg[/tex]

Bruces mass is 63kg
