A 6-kg clay ball is thrown directly against a perpendicular brick wall at a velocity of 22 m/s and shatters into three pieces, which all fly backward, as shown in the figure. The wall exerts a force on the ball of 2430 N for 0.1 s. One piece of mass 2 kg travels backward at a velocity of 15 m/s and an angle of 32° above the horizontal. A second piece of mass 1 kg travels at a velocity of 7 m/s and an angle of 28° below the horizontal. What is the velocity of the third piece?
