a)

p1 = m1 * v1 = 0,250 kg * 20 m/s = 5 Ns

p2 = m2 * v2 = m2 * 0 = 0 Ns

pundefined = p1 + p2 = 5 Ns

b)

pundefined = m2 * v2 => $$ v2 = \frac {p'} {m2} = \frac {5 Ns} {6,0 * 10^{-24}}= \frac {5} {6} * 10^{-24} kg $$

c)

0,5 * m * v ² = E 0,5 * 0,250kg * (20m/s)² = 50J

Die Energie geht in die Verformungsarbeit.
