3. A child is swinging on a swing, and having learned Physics, you decide to analyze the situation. The mass of the child is 42.3 kg. The swing is supported by two chains, which are each 3.17 m long. The tension in each chain at the lowest point is 415 N. What is the child's speed at the lowest point, and what is the force exerted by the seat on the child at the lowest point? (Please ignore the mass of the seat).
