GQ9.7 2/2 points (graded) A large firecracker explodes in mid-air into three large fragments. a) Assuming that the velocity of the center of mass is in vertical (y-) direction, what is the speed of the center of V, = 10 m/s y mass? Give your answer in m/ s. V2 = 12 m/s m , = 2.09 0.59 O my = 3.09 Oom - 10.09 Us = 3.0 m/s x 0.59 b) Is it moving up or down? C Up Down Submit Show
