A projectile mass m travels along the posotive x coordinate direction at a speed of 300 m/s breaks into three parts m1, m2, and m3. The fragments move in the x-y plane. M1 has a velocity of 200 m/s at an angle of 20 degrees above the x axsis, M2 has a velocity of 550 m/s at an angle 10 degrees above the x axsis, and M3 has a velocity 600 m/s 45 degrees below the x axsis. If M1 weighs 100 kg find M2 and M3.
