Suppose a child is sitting 5 feet from the fulcrum. Where does a 175 pound adult need to sit for the seesaw to be balance?

  • Math -

    It's a levers problem.
    So You need to know following.

    Weight1 *Distance1(from fulcrum)=W2 *D2

    What is child's weight? If 70 lb,
    70 *5 =175 * X

    So X=2
    Adult need to sit 2 feet from the fulcrum.
