The momentum of block A is +450 kgm/s and block B is -150 kgm/s After, block A has a momentum +100 kgm/s what is the momentum of block B afterwards? HELP AS SOON AS POSSIBLE PLSSS, thanx

Respuesta :


[Before]ρ₁ρ₂=[After]ρ₁ρ₂

[Before](+450)*(-150)=[After](+100)*ρ₂

[Before](-67,500)=[After](+100)*ρ₂

[After] ρ₂ = (-67,500)/(+100)

[After] ρ₂ = -675 kg*m/s
