Velocity from 0 to 4seconds

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.

Simple, don't do it. just don't go to that dock

This question is incomplete and not physics but i'm  willing to if you can give a better question

If the woman is just hanging off the bar then i think each arm will support 350n  and if she accelerates 1400n
