These forces form a force pair. Use Newton's third law, and you see that the trailer pulls back at with the same force. The answer is d.

Answer:
The centripetal acceleration of the child at the bottom of the swing is 15.04 m/s².
                      
Explanation:
The centripetal acceleration is given by:
 
 
Where:
 : is the tangential speed = 9.50 m/s
: is the tangential speed = 9.50 m/s
r: is the distance = 6.00 m
Hence, the centripetal acceleration is:

Therefore, the centripetal acceleration of the child at the bottom of the swing is 15.04 m/s².
I hope it helps you!

Answer</h2>
The physical state of the elements depends upon the <u>attraction forces </u>and their <u>kinetic energy</u>. 
<h2>
Explanation</h2>
The elements or substances are fixed with each other with the help of different chemical forces including ionic bonding, covalent bonding, H- bonding etc. The strength of these forces is also one of the factors that affect their physical natures. For example, covalent or ionic bonds are the strongest bonds than all other bonds and metals that contain these forces are mostly in solid form. The kinetic motion of electrons in the element also affects the physical state of the element and potential of bonding.
