Gegeben:

m = 0,50 kg  ; v = 100 km/h

a)

Bremsweg: x = 10cm

v² = 2ax

a = v²/2x

a = (100km/h)² / 2*10cm

a = (27,78 m/s)² / 0,2m

a = 3858,642 m/s²

F = 0.5kg*3858 m/s² = 1918.2 N = 1.918 kN b)

2.Lösung

a) F = m*a

  a = 
  v²= 2ax
  a = 
  a = Failed to parse (lexing error): \frac {27.7m/s²}{0,2m}
