Astudent throws a heavy red ball horizontally from a balcony of a tall building with an initial speed v0. at the same time, a second student drops a lighter blue ball from the same balcony. neglecting air resistance, which statement is true? the blue ball reaches the ground first. the balls reach the ground at the same instant. the red ball reaches the ground first. both balls hit the ground with the same speed. none of the above statements is true. incorrect: your answer is incorrect.

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.
