**Elena**, Thursday, October 25, 2012 at 12:44pmm1 =4.3•10^-3 kg, m2 = 22.6•10^-3 kg, h =1.4 m, L= 3.1 m., v1 =?

m1 •v1 = (m1+m2) •v,

v= m1 •v1 /(m1 + m2) .

h =g•t²/2 => t = sqrt(2•h/g)

L= v•t = v• sqrt(2•h/g),

v =L/sqrt(2•h/g),

m1 •v1 /(m1 + m2) = L/sqrt(2•h/g).

v1= L•(m1 + m2)/m1• sqrt(2•h/g) = …
