Suppose that in a lightning flash the potential difference between a cloud and the ground is 1.0×109 V?

Suppose that in a lightning flash the potential difference between a cloud and the ground is 1.0×109 V and the quantity of charge transferred is 32 C.

(a) What is the change in energy of that transferred charge?

(b) If all the energy released could be used to accelerate a 1100 kg car from rest, what would be its final speed?

1.0x10^9 V, sorry, not 1.0x109 V

32 Coulomb = 32 A*sec
E = V*C = 10^9 V*32 A*sec = 3.2*10^10 joule = 1.1*10^3/2*V^2
V = √6.4/1.1*10^7 = 7.628*10^3 m/sec

1.0×109 V ? 109 volts ? much too low.
