That depends on a few things. First, exert on what? The ground? Is the ground made of concrete? Grass? Soft dirt or mud? The reason that is important is we need to know how quickly the 200-pound object stopped in order to answer your question. How far did it sink into the ground? An inch? A half inch? Just 0.1 inch? Second, we need to know whether the object rebounded. Did it just go plop and sink into the ground, or did the object bounce back up like a rubber ball? Those two things will affect the answer. The force exerted is much greater if the object rebounds, but let us assume the object does NOT rebound. The object's kinetic energy (KE) just before hitting the ground is equal to the potential energy (PE) it had at two feet off the ground. Since PE = wh = 200 (pounds force) x 2 feet = 400 foot pounds, we can say that KE is 400 foot pounds right before impact. We know that energy is the ability to do work, and that work is force times distance (W = Fd), so we can write F = W/d. Just before impact, KE is 400 foot pounds, and after impact KE is zero. The change in KE, therefore, is 400 foot pounds. Now, let us assume the object sinks into the ground one inch, which is equal to 1/12 foot (because there are 12 inches to the foot). Hence, the force applied to the object -- or the force exerted by the object -- is 400 / (1/12) = 400 * 12 = 4800 pounds force. What if the object fell on concrete and sunk into it only one tenth of an inch? In that case the force exerted would be 400 / (0.1/12) = 48,000 pounds force, which equals 24 tons!

The force exerted by the weight depends on the acceleration due to gravity, which is approximately 9.81 m/s^2. If a 200-pound object fell 2 feet, it would exert a force of 200 pounds x 2 feet x 9.81 m/s^2. This would result in a force of approximately 3924.48 Newtons.

How much g force would 10 times earths gravity be?
Ten times Earth's gravity would produce a gravitational force equivalent to 100g (100 times the acceleration due to gravity on Earth). This extreme force would exert immense pressure on the body and could be potentially lethal.
If you exert a force of 20 newtons on a can opener and the opener exerts a force of 60newton on the can the ideal mechanica advantage of the can opener is?
The ideal mechanical advantage of the can opener is calculated as the ratio of the output force to the input force. In this case, it would be 60 newtons (output force) divided by 20 newtons (input force), which equals 3. This means that for every 1 newton of input force applied, the opener can exert 3 newtons of force on the can.
What effect would adding additional neutrons have on the force in a nucleus?
The additional neutrons don't exert electric forces. They do attract one another, and the protons, via the strong nuclear force.
How much would you weigh on if you weigh 90 pounds?
If you weigh 90 pounds, you would still weigh 90 pounds regardless of where you are. Weight is a measurement of the force of gravity acting on an object's mass, and it remains constant as long as the gravitational force is constant.
Would a zebra be best weighed in pounds or tons?
A zebra would typically be best weighed in pounds since they typically weigh a few hundred to around 1,000 pounds. Weighing them in tons would be excessive since a ton is equivalent to 2,000 pounds.
How many pounds of effort force would a user have to exert on the rope to lift the 60 lb load?
20lbs
What force would the scale exert on a 53 kg person standing on it?
The scale would exert a force equal to the weight of the person, which is the product of the person's mass and the acceleration due to gravity. So, the scale would exert a force of approximately 520 Newtons (N) on a 53 kg person standing on it (assuming g ≈ 9.81 m/s^2).
What do you call a force that you exert away from you?
Mass
How much force does one exert when lifting an object?
The force would be the weight of the object.
What liquid would exert a greater buoyant force?
A liquid with higher density will exert a greater buoyant force. This is because buoyant force is proportional to the density of the liquid displaced by the object.
If you were in orbit how much force would you exert on a scale?
In orbit, you would not exert any force on a scale since you are in free fall. This is because both you and the scale would be experiencing the same gravitational force, causing you to float weightlessly.
If a breaker bar is 2 feet long and you exert 125 pounds of force on the end of the handle approximately how many pounds of force are exerted at the drive head?
The force at the drive head would be around 62.5 pounds. This is because the force at the drive head is half of the force exerted at the end of the handle when using a breaker bar.
How much g force would 10 times earths gravity be?
Ten times Earth's gravity would produce a gravitational force equivalent to 100g (100 times the acceleration due to gravity on Earth). This extreme force would exert immense pressure on the body and could be potentially lethal.
Is the force that objects exert on each other because of their masses?
That would be "Gravity".
How do you write Fifteen hundred pounds?
It would be 1500 pounds.
What is a hundred pounds in Cockney slang?
A "ton" is Cockney rhyming slang for a hundred pounds.
How much force is needed to lift 78 pounds person into the air?
To lift a 78 pound person into the air with a constant velocity, you would need to exert a force equal to 78 pounds (the weight of the person) in the upward direction. This force is required to counteract the force of gravity acting on the person.
