A ball is dropped off a ledge How far does it fall in the second second?

It all depends on the weight of the ball but if a tennis ball was thrown it would travel 2 1/2M in 2 seconds but cannot be calculated like this because the further the ball falls the more speed it gains. However there is a trick to this question because the 2nd second is only one second itself. making the answer 1M and 10CM !

How many meters will a 2kg ball moves starting from rest fall freely in one second?
The mass is irrelevant. If the object is in free fall (that is, air resistance can be neglected), an object will fall 4.9 meters in one second.
What will drop first a big ball or a small ball?
Both will reach the ground at the same time if they were dropped at the same time in a vacuum. This is a well proven fact that the mass has no effect on the acceleration of an object in a free fall in a vacuum.
How far different size ball will roll if they are let go at the same spot on a hill?
If two round objects roll down a hill, the one with the greater mass will roll faster. If they are dropped they will fall at the same rate.
If a ball is dropped from a balloon that is 640 feet above the ground and rising at a rate of 48 feet per second find the time the ball is in the air and the speed of the ball when it hits the ground?
Let v be the velocity when the ball is at 640 feets going downwards v = 48 feet /sec let the velocity with which it reaches the ground be u then, u2=v2+2gh g = acc due t ogravity in feet/sq.sec h = 640 feet the time taken to reach the ground = time to return to 640ft + the time to fall from there Time taken to get to the ground is 8 seconds. Final velocity is 208 feet per second downwards
A rock is dropped from rest and falls for 3 seconds what is the acceleration?
The acceleration due to the earths gravitational field at the surface is on average about 9.8 m/s^2, or 9.8 meters per second per second. This means that every second you fall go 9.8 m/s faster. So if we ignore air-resistance we find that a rock dropped from rest will have a speed of 3s * 9.8 m/s^2 = 29,4 m/s.
A ball is in free fall after being dropped what will the speed of the ball after 2 seconds of free fall?
The speed of an object in free fall increases by 9.8 m/s every second. Therefore, after 2 seconds of free fall, the speed of the ball will be 9.8 m/s * 2 seconds = 19.6 m/s.
A ball just dropped is an example of?
An example of free fall due to gravity.
Does a golf ball fall when dropped on the Moon?
Yes, a golf ball will fall when dropped on the Moon due to the presence of gravity. However, the acceleration of gravity on the Moon is weaker than on Earth, so the ball will fall more slowly.
What is an example of an free fall?
A rock that is dropped, and a apple falling from a tree.Hold a ball in your hand, stretch out your arm, and drop the ball. As it is moving towards the ground, it is in free fall.
Where did the second bomb fall?
The second atomic bomb used in combat was dropped on Nagasaki.
Which will fall faster a feather or ping pong ball if dropped in a vacuum?
Both will fall at the same time in vacuum because there is no resistance.
Why does a ball dropped from a high tower fall to the base of the tower?
Due to the force of gravity. The gravitational attraction between the Earth and the ball is what causes the ball to drop.
A ball just dropped is an example of what?
A ball just dropped is an example of free fall, where the only force acting on it is gravity causing it to accelerate downwards at a constant rate of 9.81 m/s^2.
Does an object dropped from twice as high take twice the time to fall?
No, an object dropped from twice the height will not take twice the time to fall. This is because the time it takes for an object to fall depends on the initial velocity and acceleration due to gravity, not just the height from which it is dropped.
What is the kinetic energy of a bowling ball when it's dropped off of the side of a building as is continues to fall freely?
increases
What happens when a hollow plastic ball and a sollid metal ball is dropped in a vacuum and gravity is the only force?
In a vacuum with gravity as the only force, both the hollow plastic ball and the solid metal ball will fall at the same rate and hit the ground simultaneously. This is because in the absence of air resistance, the mass or density of the objects does not affect their rate of fall.
When you drop a ball what kind of energy does the falling ball have?
When a ball is dropped, it has gravitational potential energy that is converted to kinetic energy as it falls due to gravity. This kinetic energy increases as the ball gains speed during the fall.
