Ignoring the effects of air resistance, the velocity of any object dropped
near the surface of the Earth is 29.42 meters (96.53 feet) per second,
directed downward, after it has fallen 3 meters.
If you're working with situations and asking questions like this one, then
you're supposed to know by now that the mass or weight of the object
makes no difference. If you can eliminate air resistance, then the answer
is the same for a feather, a Bowling ball, and a battleship.

What is the velocity of a stone dropped of a building 318 meters?
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.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
What is the velocity of a ball that has a 3.03 second hit to the ground?
If it was thrown horizontally or dropped, and hit the ground 3.03 seconds later, then it hit the ground moving at a speed of 29.694 meters (97.42-ft) per second. If it was tossed at any angle not horizontal, and hit the ground 3.03 seconds later, we need to know the direction it was launched, in order to calculate the speed with which it hit the ground.
A 12 kg rock falls from rest off a cliff and hits the ground in 1.5 s What is the velocity?
The acceleration of gravity is 9.8 meters/sec2.In 1.5 seconds after it's dropped, any object is falling at (9.8 x 2) = 19.6 meters/sec.The mass of the rock makes no difference.
A projectile is fired horizontally from a gun that is 71.0 m above flat ground emerging from the gun with a speed of 250 ms What is the magnitude of the vertical component of its velocity as it st?
If it's fired horizontally, then its initial vertical velocity is zero. After that, the vertical velocityincreases by 9.8 meters per second every second, directed downward, and the projectile hitsthe ground after roughly 3.8 seconds.Exactly the same vertical motion as if it were dropped from the gun muzzle, with no horizontal velocity.

A rock is dropped from rest off the top of Papa John’s Cardinal Stadium. If the top row of bleachers is 88 meters high, how long will it take the rock to reach the ground What will the velocity of the rock be right before it hits the ground?

What is the velocity of a ball in meters per second that drops from a roof and the speed was at 3.03 seconds?
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
Calculate the velocity of ball just before it hits the ground when dropped from a height of 6m?
Here are two different methods to solve this kind of problem. 1) Use one of the formulae for constant acceleration. In this case, vf2 = vi2 + 2as, where vf is the final velocity, vi is the initial velocity (zero in this case), a is the acceleration (9.8 meters / second2), and s is the distance. 2) Do an energy calculation, as follows: Calculate the potential energy at a height of 6 meters, with the formula PE = mgh. Since we can assume that the entire potential energy gets converted to kinetic energy just before the ball hits the ground, solve for velocity, in the kinetic energy formula.
A stone that is initially at rest is dropped from the top of a building it falls for 5.0s before hitting the ground how tall is the building?
The building is h=.5 gt^2 meters tall; that is = .5x9.8 x25 =122.5 meters.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.

A rock is dropped from a cliff and hits the ground 6.0 seconds later How high is the cliff?
176.4 meters
Can speed be a negative value?
No because you touch yourself at night.|_ 4 VV |_Just kidding. It does!Psyche!Actually, it does not because when your mother dropped you from 2 meters above the ground, you fell at a negative VELOCITY. Speed does not specify direction, and therefore can not be negative.

What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²?
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
