A robot at the new RoboSushi restaurant accidentally drops a glass tray. When the tray hits the floor it breaks into three pieces. All the pieces explode parallel to the floor. As the plate falls, its momentum has only a vertical component, and no component parallel to the floor (i.e. the object can be considered at rest initially parallel to the floor). One piece has a mass, m1, and a velocity of 4.00 m/s [S37.0W]. A second piece has a mass, m2, and a velocity of 6.08 m/s [E24.0S]. The final piece has a mass, m3 = 2.00 kg, and a velocity of 6.40 m/s [N]. Since, the robot's programming is limited, you have been asked to determine the mass of the missing pieces. (Hint: Consider how you solve a problem with two unknowns)
