Answer:
The centripetal force acting on the child is 39400.56 N.
Explanation:
Given:
Mass of the child is, 
Radius of the barrel is, 
Number of revolutions are, 
Time taken for 10 revolutions is, 
Therefore, the time period of the child is given as:
Now, angular velocity is related to time period as:
Now, centripetal force acting on the child is given as:
Therefore, the centripetal force acting on the child is 39400.56 N.
Newton’s second law of motion is force equals mass times acceleration.
F = m•a
An example of this would be hitting a ball. If you hit the ball, it will move however fast you hit the ball. The harder you hit the ball, the faster it will move.
hope this helps and brainliest please

<span>The polarity of a water molecule
comes from the uneven distribution of electron density of hydrogen and oxygen
atom. The oxygen in the water molecule is more electronegative than the
hydrogen. Water has a <u>partial positive charge near the hydrogen atom and a
partial negative charge near the oxygen atom</u>. The result of this
electrostatic attraction results in the bond called hydrogen bond. Also, because
of this bond, it has the ability to dissolve most of the solutes due to its
polarity and bonding.</span>
It is probably transversal.
The particles vibrate perpendicular to the direction of an energy transmission.
I hope this helps.
