The kinetic energy of a thrown baseball is: a. over a billion times greater than its rest energy
b. greater than its reset energy by several times
c. about the same as its rest energy
d. a little less than its rest energy
e. less than a billionth of its rest energy
f. impossible to estimate

magnets not strong enough

explanation:

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
