The book acquires (2.5 x 3) = 7.5 joules of gravitational potential energy.
You'll have to do at least that much work, plus whatever it takes to account
for the inefficiency of motions, muscle metabolism etc.

How much work is done if you lift a box weighing 100n on to a shelf that is 2 meters high?
Work = force x distance = 200 joules
A force of 20 N is required to lift a box the box is lifted from the floor to a shelf that is 2 m high the amount of work done is?
Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J
What sort of energy does a book have if it falls off a high shelf?
Before it falls it has gravitational potential energy. While it falls, the potential energy gets converted to kinetic energy. Part of this gets dissipated by friction - mainly converted to heat. Once it hits the ground, all the energy will be converted to heat.
Do a stretched spring and a box on a high shelf both have potential energy why or why not explain you answer?
yes because is more
What kinda of energy is a box of matches?
A box of matches on a high shelf has gravitational potential energy.A box of matches falling from the high shelf has kinetic energy.A box of matches on fire has heat, sound and light energy.A box of matches on its own has chemical potential energy.
What form of stored energy does a book have while it is still on a high shelf?
How does a book on a higher shelf have more potential energy than a book on the lower shelf
Is Book on a high shelf chemical or potential energy?
Potential energy.
What is the mass of a book on a 2 meter high shelf with 20 joules of potential energy?
10
If you perform 40 joules of work lifting a 10-N bix from the floor to a shelf how high is the shelf?
The height of the shelf can be calculated using the formula: work done = force x distance. In this case, the work done is 40 J, the force is 10 N, so the distance (height of the shelf) can be calculated as 40 J / 10 N = 4 meters.
00 joules of work was done lifting a 200 newton box to a shelf directly above the box. How many meters high was the shelf?
0 / 200 = 0 meters.
What are the two ways on how to reach a book in the library?
Basically, you reach for a book in the library with your hand. So i suppose the two ways are; 'standing on the floor' or 'standing on a ladder' if the book is on a high shelf.
How much work is done if you lift a box weighing 100n on to a shelf that is 2 meters high?
Work = force x distance = 200 joules
Why does a book on a high shelf have more potential energy than on a low shelf?
Since potential energy equals mgh. When h, height increases potential energy also increases. If h is 0 then p.e is 0/
How high does the sensor for a Wii have to be?
Only as high as a third shelf.
What is the standard height of the space between the desktop and the bottom of a shelf?
it depends if your cealing is high you will probably have a big shelf.
A force of 20 N is required to lift a box the box is lifted from the floor to a shelf that is 2 m high the amount of work done is?
Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J
Where can I buy a ready-made book shelf?
Sears, The Brick, Leon's and The Bay each sell top quality book shelves made of high quality material in their furniture departments. Many are special ordered to customers specifications.
