The following questions present a twist on the scenario above to test your understanding. suppose another stone is thrown horizontally from the same building. if it strikes the ground 55 m away, find the following values. (assume angles above the horizontal are positive.)
(a) time of flight
(b) initial speed

Yup no bull frogs here man

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.
