Transcribed Image Text:An m = 6.90-kg clay ball is thrown directly against a perpendicular brick wall at a velocity of 22.0 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 2630 N for 0.110 s. One piece of mass m₁ = 2.90 kg travels backward at a velocity of 10.6 m/s and an angle of = 32.0° above the
horizontal.
A second piece of mass m₂ -1.90 kg travels at a velocity of 8.70 m/s and an angle of 28.0° below the horizontal.
