**Elena**, Friday, November 30, 2012 at 3:30amThe law of conservation of linear momentum

vector p₁ +vector p₂ =vectorp₁`+vector p₂`

Projections on the axis x and y

p₁⒳ +p₂⒳= p₁`⒳+p₂`⒳

p₁⒴ +p₂⒴= p₁`⒴+p₂`⒴

3.44=5.16•cos45 + p₂`⒳

6.88=5.16•sin45 + p₂`⒴

p₂`⒳ =3.44-5.16•0.707= - 0.17

p₂`⒴=6.88-5.16•0.707= 3.28

p₂=sqrt{ p₂`⒳²+p₂`⒴²}=…

tanβ = p₂`⒴/ p₂`⒳
