A ball with a mass of 230 g is tied to a light string that has a length of 2.00 m. The end of the string is tied to a hook, and the ball hangs motionless below the hook. Keeping the string taut, you then move the ball back and up until it is a vertical distance of 1.27 m above its equilibrium point. You then release the ball from rest, and it oscillates back and forth, pendulum style. What is the highest speed the ball achieves in its subsequent motion

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.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )

Tons?
