You are given the mass of the book with an initial
height of 0.77m. You are also given the final height of the book, 2m above the
floor. The problem requires you to find the work done on the book. It is said
that work is equal to force times distance. And that force is equal to mass
times acceleration due to gravity.
W=Fd
W=mgd=mgh
W=(1.7kg)(9.8m/s^2)(2m-0.77m)
W=20.49J
<span>The work is equal to 20.49J.</span>
<span>Our body shape, production of red blood cells, and the protection of major organs in the body are all in the performance of the skeletal system. Supplying our blood oxygen, if this system fails our body will cease to function entirely from the lack of oxygen and the carbon dioxide filling us inside.</span>

A command economy<span> is a system where the government, rather than the free market, determines what goods should be produced, how much should be produced and the price at which the goods are offered for sale.</span>
the force in each of the chains holding the trapeze bar is D. 330 N
Her weight has to be divided evenly so, divide 660/2= 330 N
