Homework Statement
[/B]
Conservation of momentum of x components
[itex] 10(20Cos(-30)) + 5(5Cos60) = 10v_{f}Cos(α) + 5v_{f}Cos(β) [/itex]
[itex] 185.7 = 10v_{f}Cos(α) + 5v_{f}Cos(β) [/itex]
Conservation of momentum of y components
[itex] 10(20Sin(-30)) + 5(5Sin60) = 10v_{f}Sin(α) + 5v_{f}Sin(β) [/itex]
[itex] -78.3 = 10v_{f}Sin(α) + 5v_{f}Sin(β) [/itex]
Homework Equations
Conservation of momentum in x:
(mv)1ix + (mv)2ix = (mv)1fx + (mv)2fx
Conservation of momentum in y
(mv)1iy + (mv)2iy = (mv)1fy + (mv)2fy
The Attempt at a Solution
x components
[itex] 185.7 = 10v_{f}Cos(α) + 5v_{f}Cos(β) [/itex]
and
y components
[itex] -78.3 = 10v_{f}Sin(α) + 5v_{f}Sin(β) [/itex]With two equations, each with two unknown velocities and two unknown angles. It just seems like there is not enough information to algebraically solve for the final velocities and angles.
