B. jerome plays middle linebacker for south's varsity football team. in a game against
cross-town rival north, he delivered a hit to north's 82-kg running back, changing his
eastward velocity of 5.6 m/s into a westward velocity of 2.5 m/s. determine the
impulse delivered to the running back.
a. 210 kgm/s
b. 250 kgm/s
c. 460 kgm/s
d. 670 kgm/s

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.
