A 2 kg object travels at 10 m / s and collides with a second 10 kg object that was at rest. After the collision, the 2 kg object moves backwards at 2 m / s.
a) Calculate the initial momentum and kinetic energy. Which of the two quantities is always conserved in a collision?
b) How much is the speed of the second object after the crash worth?
c) How much energy degrades during the crash?
d) If it were an elastic shock, what would be the final speeds?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
