When the mother finds the distance l from the previous part it turns out to be greater than lend, the distance from the pivot to the end of the seesaw. hence, even with the child of weight w at the very end of the seesaw the twins exert more torque than the heavier child does. the mother now elects to balance the seesaw by pushing sideways on an ornament (the circle above the center) that is a height h above the pivot. with what force in the rightwards direction, fx, should the mother push? note that if you think the force exerted by the mother should be toward the left, your final answer fx should be negative.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
