if a baseball and a cannonball are dropped from the same height at the same time, another is no air resistance, which ball will hit the ground first

They hit at the same time. In a vacuum (no air resistance) all objects near Earth's surface accelerate at the same rate g ≈ 9.8 m/s² regardless of mass. With initial velocity zero and drop height h:

h = 1/2 g t² → t = sqrt(2h/g),

so the fall time depends only on h and g, not on the object's mass. (With air resistance the denser/heavier cannonball would usually land first.)
