Jaka była wartość siły która zmieniła się w czasie 10s, pęd ciała to 5kg/ms
t = 10sp = 5 kg * m/sF = ?F = m *a ; ale a = V / t F = m * V / t ; ale m *V = p F = p /tF = [kg * m/s *s / s ] = [ kg * m/s^2] = [ N]

t = 10s
p = 5 kg * m/s
F = ?
F = m *a ; ale a = V / t
F = m * V / t ; ale m *V = p
F = p /t
F = [kg * m/s *s / s ] = [ kg * m/s^2] = [ N]
