Question

The forces acting on a child sitting in a seat are described

by the free-body diagram shown.
What is the net force acting on the child?
0-100 N
Ο ΟΝ
Fx = 100 N
O 100 N
200N
F, = -100 N

Answer 1

F-net = 0 N

Step-by-step explanation:

When there is an unmoved object, we know that there is always a gravitational force present on the object that pushes it down on the ground. But according to Newton's 3rd law (there is always an equal and opposite force for any action), there is a force acting on the child to keep it from falling.
