A mother pushes her child on a swing so that his speed is 9.7 m/s at the lowest point of his path. The swing is attached to a point 2.05 m above the child’s center of mass when the swing is motionless. What is the centripetal acceleration of the child at the low point in m/s2?  ac = 45.89      But what is the magnitude of the force that the child exerts on the seat at the lowest point if his mass is 19.5 kg in N?  Fc =
