6) A child with a weight of 470.0 N grabs onto the end of a rope whose length is 1.80 m. The child swings back and forth, as a pendulum. As the rope swings vertically, the speed of the child is 0.800 m/s. a) What is the acceleration of the child (magnitude and direction), at the moment when the rope is vertical? b) At the moment when the rope is vertical, what force does the rope exert on the child, in order to keep the child hanging onto the rope?
