5. Let’s tie this all together. It makes sense that, if the rope force remains greater than the gravitational force, the child keeps speeding up; and if the rope force becomes less than the gravitational force, the child slows down. By this line of intuitive reasoning, what happens to the child’s motion if the rope force equals the child’s weight, i.e., if the rope force “compromises” between being greater than and being less than the child’s weight? Explain.
6. Does Newton’s second law agree with your answer?
