A bag of wheat weighs 200kg. To what height should it be raised so that its potential energy may be 9800 joules?

Answer :
potential energy (PE) = m *g *h
m= mass of object (kg)
g= gravity = 10 m/s2
h= height (m)
PE = m *g *h
9800 = 200 * 10 *h
9800= 2000 h
h= 4.9 m

Which combiation of features will have the greatest gravitational potential energy?
A large mass raised to a great height will.
What is the potential energy of a 100kg object when it is raised to a height of 5.00m?
PE=mgh (mass x gravity x height). Use 9.8 for gravity. Answer is in joule.
What energy does an object have because of its position?
It depends on the circumstances but usually such energy is referred to as potential energy. For example your position in a gravitational field may determine the gravitational potential energy. Likewise your position in a spring system may determine the potential energy of the spring.
How much energy is 500 joules?
500 joules is equal to 368.78 ft-lbf. For example, an object has 500 joules of kinetic energy, when its mass is 10 kg (~22 lbs) and it is traveling at 10 m/s (36 km/h or ~38.2 ft/s). Second example: The muzzle energy of a traveling 9mm bullet is around 500 joules. Third example: An object with mass of 5kg (11 lbs) and which is raised at 10 metres (32.8 ft) has around 500 joules of potential energy. So, 500 joules is quite much. Getting hit with an object which has 500 joules of kinetic energy can be lethal.
The energy of position is what kind of energy?
That is called potential energy. For example, in the case of gravitational potential energy: If an object is raised, its potential energy increases.
What would the gravitational potential energy be if the bucket of water were raised twice as high?
GPE = mass * acceleration of gravity * height. Original GPE : m*g*h Joules if you double the height, you get m*g*2h Joules, or 2*m*g*h -- twice the GPE.
What is the potiential energy of the 85 kg rock?
For every meter it's raised, it gains 833 more joules of gravitational potential energy.
What is the potential energy of a mass of 500 g raised to a height of 2 m?
The formula for working out Potential enery is: PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons) - mass should be in Kg's - and height in meters - final answer should be in Joules (J) Therefore substitute it in :-) Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters) Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters
What are Non examples of mechanical energy?
Potential Energy. That is, Energy of Position. An Object raised to a greater height than its original position will show an Increase in its Potential Energy.
Which combiation of features will have the greatest gravitational potential energy?
A large mass raised to a great height will.
How do you find potential energy?
gravitation potential energy can be found by the formula EP=mgh, where EP potential energy, m is the mass of the object for which the potential energy is to be found,g is the acceleration due to gravity, h is the height to which the object is raised.
What are the other uses of potential energy?
it is used in generating electricity when water is raised to a height to make it fall on a turbine it is having potential energy stored in it.It has many other forms as elastic ,gravitational,vibrational potential energy.
What is the potential energy of a 100kg object when it is raised to a height of 5.00m?
PE=mgh (mass x gravity x height). Use 9.8 for gravity. Answer is in joule.
What energy does an object have because of its position?
It depends on the circumstances but usually such energy is referred to as potential energy. For example your position in a gravitational field may determine the gravitational potential energy. Likewise your position in a spring system may determine the potential energy of the spring.
What is the potential energy given to the 50.0 kg hammer of a pile driver when it is raised 4.00m?
P.E. = M G H = (50) x (9.8) x (4) = 1,960 joules
