Consider the motion of a bullet fired straight down from the top of a high cliff.
Consider only the motion after the bullet has
left the barrel of the gun and before it hits the
ground. Ignore air resistance.
What is the magnitude of the acceleration
of the bullet during this motion?
1.Equal to 9.8m/s^2
2. First less than 9.8 m/s², then greater
3. More than 9.8 m/s2
4. Equal to 0
5. First greater than 9.8 m/s2, then less
6. Less than 9.8 m/s2
Who is the answer !?

Ithink your answer is d

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.
