Answer:
220.7
Explanation:
distance traveled is 1.5*5=7.5m
PE gain is MGH=3*9.81*7.5=220.7
The Earth's gravitational pull and the table's force are of equal magnitude and in opposite directions, they balance each other.
<u>Explanation:</u>
A book placed on a surface have two forces acting on it which are, a force that pulls it toward the ground in a downward direction, that is gravitational pull and a second which is acted on the book on upward direction making a balance on the object.
This follows Newton’s third law of motion that states every action has an equal and opposite reaction.

13 g —> 0.013 kg
KE = 1/2(m)(v)^2
KE = 1/2(0.013)(8.5)^2
KE = 0.47 J
