Part B Determine the direction of the velocity of the third fragment immediately after the explosion. .=?(above the horizontal)

A 236kg projectile, fired with a speed of 128m/s at a 63.0 angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally
