Well, 40 percent of 250 I guess! Which, if you are not good at arithmetic is 100 Joules.

What is the potential energy of an object that has a mass of 40 kg at a height of 17 meters?
The object's potential energy is 6,664 joules.
How does kinetic energy and potential energy switch?
work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?
What is an object's kinetic energy if air resistance is not a factor and weighs 0.6 kg and its potential energy is 27 joules?
The object's kinetic energy can't be determined from the given information. Kinetic energy = (1/2) (mass) (speed)2 The question gives the object's mass, but we need its speed too.
Object hanging on a tree a kinetic or potential energy?
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
How is potential and kinetic energy used?
potential energy is the energy that an object has stored up. kinetic energy is an object in motion. :) hi ppl :)))))))
What is the potential energy of an object that has a mass of 40 kg at a height of 17 meters?
The object's potential energy is 6,664 joules.
What is the potential energy of an object if its mass is 1500 g and the height of its drop is 99 cm?
The object's potential energy is 14.55 joules.
The potential energy of a 50 newton object resting on the edge of a cliff 30 meters high is?
The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.
Suppose a falling object loses 7J of potential energy. How much kinetic energy will it gain?
From what I understand: PE - Potential Energy (mgh) KE - Kinetic Energy (1/2 mv2) If one dismisses the friction with air (conservation of energy), a loss of 7 joules for potential energy means a gain of 7 Joules in kinetic energy.
How do you Calculate the mass of an object of 180 joules and rest at 15 meters from the ground?
How do you calculate the mass of an object that has a potential energy of 180 joules and rest at the top of a hill 15 meters from the ground?
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
The potential energy of a 50 newton object resting on the edge of a cliff 30 meters high is .?
1500 joules
What is the gravitational potential energy of a 3 kilograms object 8 meters above the ground?
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
When you lift an object energy is transferred to an object which gives the object?
When you lift an object, the energy transferred to the object is called gravitational potential energy.
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.
When an object falls which energy changes to?
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
What is the gravitational potential energy of an object equal to?
It is the product of the mass of the object in Kg, the gravitational acceleration which is 9.81 m/sec2, and the height of the object above earth's surface in meters. Result is in Joules
