A 224-kg projectile, fired with a speed of 116 m/s at a60.0 angle, breaks into three pieces of equal mass at thehighest point of its arc (where its velocity is horizontal). Twoof the fragments move with the same speed right afterthe explosion as the entire projectile had just before theexplosion; one of these moves vertically downward and theother horizontally. Determine (a) the velocity of the thirdfragment immediately after the explosion and (b) theenergy released in the explosion.
