Jake throws a ball straight down off a balcony. He throws the ball with a downward initial velocity of 3.0 m/s. Which of the following would be an
appropriate downward acceleration for the ball as it falls to the ground?
(ignore air resistance)

the answer is 46 mls because when you add the speed per second it increses the speed

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
