Ignoring any effects due to air resistance, the speed of the stone is zero at the instant it's dropped, and increases steadily to 78.98 meters per second when it hits the ground. The velocity is directed downward throughout the experiment.

If you simply release an object, the initial velocity is always zero.

Diving is generally taken to mean that you start from rest and jump. If Superboy dives off the building, he would initially have had zero velocity, relative to the building.
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.
I think its the dropping of a golf ball off a building! This is because the formula for velocity when something is dropped is a quadratic formula, that is of degree 2.

The displacement and velocity of a rock that is dropped from rest after 4s, is 6 km/h. This can vary depending on the speed of the rock, and the surroundings.
