Homework Equations
conservation of total momentum
M1V1+M2V2 = MtotVf
The Attempt at a Solution
I tried using the COTM
as such:
x: M1V1iCOSΘ1+M2V2SINΘ2=MtotVf
y: M1V1iSINΘ1+M2V2COSΘ2=MtotVf
then dividing 1/2:
COTΘ1 + TANΘ2 = 1
Θ2 = TAN-1(1-COTΘ1)
After plugging in the values I am getting Θ2 = -10.85°
What am I doing wrong?
