A 30 lb projectile is launched in the xy plane with a velocity of 200 ft/s at an angle of 70° with the horizontal (x) axis. At a time of 4 s after launch, it explodes into three equal pieces A, B, and C. A has velocity (100i + 50j – 100k) ft/s and B has velocity (-200i – 50j) ft/s. What is the velocity of C?
