The amount of potential energy of a 5.0-kilogram book that is moved to three different shelves on a bookcase would be 49 Joules ,73.5 Joules, and 98 Joules respectively.
Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.
Similarly, the total potential energy of the crane lift would be
PE = m*g*h
The potential energy of the book at 1.0 m is (5x9.8x1)= 49 Joules
The potential energy of the book at 1.5 m is (5x9.8x1.5) =73.5 Joules
The potential energy of the book at 2.0 m is (5x9.8x2)=98 Joules
Thus, the amount of potential energy of a 5.0-kilogram book that is moved to three different shelves on a bookcase would be 49 Joules,73.5 Joules, and 98 Joules respectively.

If the answer is for Ed genuity :
Fill in the blank below with the word that best completes the sentence.
(blank ) determine how cells are differentiated.
answer could be either : ⇒ Genes, Gene, gene, genes
The answer has the be the fourth option "the object is not accelerating." By looking at the graph you would see the the velocity is constant meaning it staying the same and its not increasing or decreasing which takes out the first, second, and third option. So, since how the velocity is not increasing the object is not accelerating or the fourth option.
Hope this helps!
sense the time shown is increasing but the velocity is neither increasing or decreasing then the answer would have to be D.
Answer:c is the answer every 2 hours A is just plain no B four hours is too long and D is a no you need to rest

Explanation:
Answer:
Inertia is the tendency or ability of a body to remain at rest or in uniform motion along a straight line in the absence of any external force. It is the reluctance a body displays when agitated or encountered by an external.
By the law of inertia, an object will always remain in its position of rest or state of uniform motion along a straight line until it is engaged with an external force.
To put it in other words;
When an object is at rest, it will want to remain at rest. If it becomes engaged with an external force it will display some reluctance before it changes its mechanical state.
Similarly, when an object is in uniform motion, it will want to continue with the motion. If an external force then interrupts it, it will also display some reluctance. This reluctance is in the form of it wanting to continue its motion irrespective of the force.
So therefore if I am moving fast on a skateboard and suddenly I become interrupted with a force, by the law of inertia my tendency is to continue the motion and this makes me exhibit reluctance in responding to the force. This reluctance will then make me to topple over and fall off if there is nothing to quickly hold unto. The more massive I am, the greater the effect of the topple. The inertia of an object is proportional to its mass.
