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 my = 1.60 kg travels at a velocity of 8.40 m/s and an angle of 28.0 below the horizontal. m a) What is the speed of the third piece? Submit Answer Incorrect.
