Detailed explanation-1: -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? The balls land at the same time.
Detailed explanation-2: -Both of the balls will hit the ground at the same time because gravity is the same. The correct term here is acceleration due to gravity. It is constant.
Detailed explanation-3: -As gravity is the only force in both cases, both balls will hit the ground at the same time.
Detailed explanation-4: -What it shows: The horizontal and vertical motions of a projectile are independent of each other. So two objects falling under the influence of gravity from the same height will reach the ground simultaneously, regardless of their horizontal velocities.
Detailed explanation-5: -Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
