Homework Statement
An object at rest explodes into three pieces. Two of them are equal in mass and break off at an angle of 85.3° to each other, both with a speed of 33.2 m/s. The last piece has 4 times as much mass as each of the other pieces. What is the magnitude of the velocity of the last piece?
Homework Equations
pf = pi
m1 = m2
m3 = 4*m1
v1 = v2 = 33.2 m/s
The Attempt at a Solution
I think that i need to consider the momentum that is conserved as components in the x and y direction. but I am not too sure how to draw out my picture to get my angles.
y: pf=pi
0 = m1cos(4.7)(33.2) + (4m1)sin[tex]\theta[/tex]
x: pf=pi
0 = m1(33.2) + v3(m3)(cos[tex]\theta[/tex]) + m1sin(4.7)(33.2)
im not sure if I am approaching this correctly...?
