You are driving a metric car that has a speedometer that displays in meters per second. When you look down at your speedometer, you see that it reads 23 m/s, then 7.4 s later you look down and it reads 13 m/s. What is your average acceleration over those 7.4 s?

The answer would be a

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.
