The speed is 44.4... repeating metres per second.
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
9.8 meters per seconds squared in the downward direction.
Disregarding air resistance, what is the speed of a ball dropped from 12 feet just before it hits the ground? (Use 1 ft = 0.30 m, and use g = 9.8 m/s2.)
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.

4 seconds
Because the horizontal and vertical motion of an object are separate. This means that a thrown object will accelerate with the same amount of acceleration as a dropped object (about 9.8 m/s2 acceleration due to gravity) causing them to hit the ground at the same time
Its acceleration is always the same - the acceleration of gravity at 32 ft/sec/sec - no matter what distance it is during drop, until it hits the ground.

Dropped objects hit the ground at the same time (as long as they're dropped from the same height) because the acceleration of gravity is constant. On earth, it's 9.8 meters per second (32.2 feet per second) every second.
both reaches the ground at the same time because in the moon there occurs free fall.
