A baseball is popped straight up into the air and has a hang-time of 8.24 s. Determine the height to which the ball rises before it reaches its peak.
(Hint: the time to rise to the peak is one-half the total hang-time.)

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
