Write out the governing equation:
y = kx.
Take any point from the given table. You haven't shared the table, so I will invent a point: (2, 9).
Then find k: k = 9/2 Then the equation becomes y = (9/2)x.
Now let x = 7 and find y: y = (9/2)(7) = 63/2
Answer: y = 63/2
In order to achieve an equilibrium some of momentum should be zero about the axis of rotation.
Suppose, the 10-kilogram child is placed X meters away from the axis of rotation.
Now, according to the question
17x2+10X-20x2=0
X=0.6m
Child should sit 0.6m away from the axis of rotation towards 17 Kg child.
