If air resistance can be ignored, the acceleration is 9.82 meters per second square. Note that to get this result, neither the mass of the book, nor the height from which it is dropped, is relevant.

∙ 11y agoacceleration is g = 9.80 m/s^2. W =mg so W = 2.26 kg x 9.80 m/s^2 = 22.1N

What is the potential energy of a book with mass of 2 kg book sitting on a shelf 2 meters above the ground?
Just use the formula for gravitational potential energy:GPE = mgh (mass x gravity x height) Gravity is about 9.8 meters/second squared. Since all units are SI, the answer will be in joules.
How could a piece of paper and book hit the ground at the same time?
-- If they're dropped in a place where there is air, then that could be accomplished byeither dropping the paper some time before the book, or from a height much lower thanthe height from which the book is dropped.-- If they're dropped in a place where there is noair, then all you have to do is dropthem at the same time from the same height. Without air, they fall together, and reachthe bottom at the same time.
What is the potential energy of a book with mass of 2 kg and a height of 15 meters use pemgh?
The book's potential energy is 294 joules.
Why is putting a book bag on a desk a form of energy?
A book bag on a desk has potential energy. That potential energy is due to its height above the ground. That potential energy is given by the formula Ep = mgh, where m is the object's mass, g is the acceleration due to gravity, and h is the height.
How many joules of potential energy does a 1-N book gain when it is elevated 8 m?
Use the formula PE = mgh, that is, potential energy = mass x gravity x height. If mass is in kg, gravity = about 9.8 meters per second square, and height is in meters, then the answer will be in Joules.
In the absence of air resistance how would the acceleration of 1.5 kg book and tha acceleration of 15 rock differ if the objects dropped from the same height?
they would not differ

If a student drops a book having a gravitational potential energy of 5 joules from a height of 1.1 meters what is the mass of the book?
The book has a mass of 0.46kg
Why does the book fall on the floor before the paper does if dropped at the same time from the same height?
air resistance is everything, if both were dropped at the same time from the same height in a vacuum, they would accelerate equally, hitting the floor at the same time..acceleration (a) is given by:a = force / mass.force (down) is given by mass (kg) * acceleration due to gravityregardless of the mass, the acceleration in a vacuum would be the same..Once air is introduced however, any motion would be resisted by the air, according to the equation: force (up) = (velocity squared * drag coefficient).so, net force available for acceleration once in motion, at a given velocity = force (down) - force (up).if you assume same drag coefficient for both, at any given velocity, lighter object will have less acceleration, leading to heavier object hitting the floor first.notes:terminal velocity is where force down = force up.for same drag coefficient, more massive object will have greater terminal velocity..guess at drag coefficient for book / paper = 0.005

What will fall faster a book or a marble?
If they're both dropped from the same place, on the same planet, then they'll both experience the same acceleration, and hit the ground with the same speed at the same time.
If a 3 Kg book falls from a shelf and lands with a speed of 4.8 meters per second what is its height?
Approximately 2.35 m The mass of the book is irrelevant in this question (since the book will accelerate with the same velocity regardless of its mass). To find the books height, we need to first find the time, t, which it fell. Time and velocity, v, are governed by the equation: v=a*t, assuming initial velocity is zero. Plugging in v and 9.8 m/s2 (the acceleration due to gravity), we get: 4.8=9.8t t=4.8/9.8, which equals approximately .49 seconds. Distance, d, for an object with constant acceleration is given by the following equation: d=a*t2, assuming initial velocity is zero Plugging in a and t gives the following: d=9.8*(.49)2=2.35 meters

How many feet high is one story?
A story is a narrative which may or may not be true. It has no height - unless you consider the height of the book in which it appears. Each story of an average building is about ten feet (three meters).
