An m = 6.60-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 2620 N for 0.110 s. One piece of mass m = 2.60 kg travels backward at a velocity of 10.9 m/s and an angle of = 32.0 above the horizontal. A second piece of mass m = 1.60 kg travels at a velocity of 8.40 m/s and an angle of 28.0 below the horizontal. a) What is the speed of the third piece? 45.6 m/s Submit Answer Incorrect. Tries 5/99 Previous Tries b) What is the direction of the third piece? (Use positive values for an angle above the horizontal, and negative for below the horizontal.) -4.5 deg Submit Answer Incorrect. Tries 1/99 Previous Tries m 22 m/s m m2 32 28
