The force exerted by the seat on the child at the lowest point is 700 N
<h3>
What is Moment ?</h3>
The moment is the product of a force and its perpendicular distance. It is measured in Nm
Given that a 40.0-kg child swings in a swing supported by two chains, each 3.00m long. The tension in each chain at the lowest point is 350N .
Since it is given that we should ignore the mass of the seat, the only force acting downward will be the weight of the child.
One of the criteria to reach equilibrium is that, sum of the upward forces will be equal to the sum of the downward forces. Otherwise, the child will tuple.
The force exerted by the seat on the child at the lowest point will the two upward forces on the tension. That is,
F = 350 + 350
F = 700 N
Therefore, the force exerted by the seat on the child at the lowest point is 700 N
