The ball would take approximately 4 seconds to hit the ground, neglecting air resistance. This calculation is based on the constant acceleration due to gravity (9.8 m/s²), assuming the ball is dropped and not thrown.
The ball had potential energy before it was dropped. This potential energy was due to its position above the ground.
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
When a ball is dropped, the energy involved is primarily gravitational potential energy being converted into kinetic energy as the ball accelerates towards the ground. When the ball hits the ground, some of this kinetic energy is transferred to the ground as impact energy.
A 0.650 kg basketball is dropped out of a window that is 6.46 m above the ground. The ball is caught by a person whose hands are 1.32 m above the ground. How much work is done on the ball by its weight?
The force that pulls a ball to the ground after being dropped is gravity. Gravity is the natural force of attraction between two objects with mass, in this case, the ball and the Earth.

Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.

Who has dropped the ball? The referee?! If the referee drops the ball after he interrupted the game the ball is in play when the ball touches the ground. It isn't allowed to score a goal directly from a dropped ball, two players have to touch the ball before the goal counts.
A ball bounces when it is dropped because of the force of gravity pulling it down and the elasticity of the ball's material. When the ball hits the ground, some of its energy is transferred into the ground as heat and sound, causing it to eventually come to a stop.
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.
