An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 33.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored.
Part A. What is the initial speed of the egg? (m/s)
Part B. How high does it rise above its starting point? (m)
Part C. What is the magnitude of its velocity at the highest point? (m/s)
Part D. What is the magnitude of its acceleration at the highest point? (m/s^2)

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.

Sorry i don’t know what to do
