A 39.0-kg child swings in a swing supported by two chains, each 2.92 m long. The tension in each chain at the lowest point is 428 N. (a) Find the child's speed at the lowest point. 7.59 Consider all the vertical components of force acting on the swing when it is at its lowest point and relate them to the acceleration of the swing at that instant. m/s (b) Find the force exerted by the seat on the child at the lowest point. (Ignore the mass of the seat.) 1238.59 Consider what exerts the force referred to in the question and how that is related to the various forces acting on the child. N (upward)
