PLEASE ANSWER ASAP!! 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?

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

+10 that is always the common denominator
