1. The problem statement, all variables and given/known data 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? 2. Relevant equations pf = pi m1 = m2 m3 = 4*m1 v1 = v2 = 33.2 m/s 3. 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 im 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 im approaching this correctly...?
