How do you calculate the speed of an object that weighs 140 lbs and falls for 8 feet 8 inches?
Assuming the object is falls under gravity, from a state of rest, and that all other forces are negligible,
v2 - u2 = 2gs where
v = final velocity
u = initial velocity = 0
g = acceleration due to gravity = 32 feet/sec2
s = distance travelled = 8 ft 8 in = 82/3 feet
so v2 = 2*32*26/3 = 554.66... ft2/sec2 so that v = 23.55 ft/sec

What happens to an object that falls?
when an object falls is it reactin to the force of gravity?
How do you calculate the horizontal distance traveled by an object if you are given the horizontal velocity and time in the air?
You cannot because you do not know how long before the object falls to the ground and so stops moving.
Describe a situation in which gravity cause a change in velocity?
You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.
The amount of gravitational potential energy released as an object falls depends on?
the height from which it falls and the mass of the object. The formula for gravitational potential energy is GPE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height from which the object falls.
What factors affect how an object falls?
wind resistance, and gravity, mass does not in any way contribute to how an object falls.
Is your child overweight if she weighs 86 pounds and is 5 feet and 2 inches tall?
no. the average weight for a twelve year old that is five feet and two inches tall is anywhere from 85-95 lbs. your child falls right in the range.
When an object falls freely the kinetic energy of the object will?
It will decrease if the object moves upward; decrease if the object moves downward.
Why does an object accelerate when it falls toward as the earth's surface?
An object accelerates when it falls towards the Earth's surface due to the force of gravity acting on it. Gravity pulls the object towards the center of the Earth, causing it to increase in speed as it falls.
What happens an object falls?
It falls, accelerating constantly until it hits the ground.
What happens when a object falls?
When an object falls, it accelerates due to gravity pulling it downwards. As it falls, the object's potential energy is converted into kinetic energy, increasing its speed. The object will continue to fall until it reaches the ground or encounters another force that counteracts gravity.
