A cannonball of mass 21.7 kg is shot into the air at an angle of 45 degrees with respect to horizontal. At the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece this is 1/3 the original mass, and a larger piece that is 2/3 the original mass. The smaller piece ends up retracing its original trajectory and landing right back at the spot where the cannonball was originally launched, 28.1 seconds after it was launched. How far from the launch site does the larger piece travel
