An object located at the origin and having mass M explodes into three pieces having masses M/4, M/3, and 5M/12. The pieces scatter on a horizontal frictionless xy-plane. The piece with mass M/4 files away with velocity 5.0 m/s at 37∘ above the x-axis. The...

Ok...I got that the angle theta from the positive x-axis is = 268 degrees (for the third piece). Am I on the right track? Thank you!
