Transcribed Image Text:A 243-kg projectile, fired with a speed of 112 m/s
at a 67.0 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.
