Pls Help I will award brainiest to the person with the best answer!!

Max takes lucky nickel to the wishing well before his physics exam. Eager to review, he decides to calculate the depth of the well as he wishes. He pulls out his phone starts the stopwatch and flips the coin up into the air. the coin reaches a maximum height of 2.5 meters before travelling down the well shaft. The total time from flip to splash is 3.7 seconds. A. What velocity did the coin have when it left max's hand? B. How far down from Jadens hand is the water surface?

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.

Ibelieve the answer is b
