A 5.00 kg ball, rolling at 3.02 m/s, strikes a another ball that is traveling at 1.55 m/s in the opposite direction. The total momentum in the system is 11.33 kgm/s. Assuming conservation of momentum, what is the mass of the second ball?

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
