a)

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

p₂ = m₂ * v₂ = m₂ * 0 = 0 Ns

p^| = p₁ + p₂ = 5 Ns

b)

p^| = m₂ * v₂ => [math] v2 = \frac {p'} {m2} = \frac {5 Ns} {6,0 * 10^{-24}}= \frac {5} {6} * 10^{-24} kg [/math]

c)

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

Die Energie geht in die Verformungsarbeit.
