Grob Pi mal Kante mit Rundungen:
E_potentiell = E_kinetisch
m g h = 1/2 m v²
h = 1/2g v²
v_0 = 85km/h = 23,6 m/s
v_22.5° = v_0 * sin(22.5°)
v_y = 9m/s
h = 4,1m (plus 1,8m = 5,9m) *stimmt*
Fallzeit
h = 1/2 g t²
t = sqrt( 2 h / g) = 1,1s
*falsch*
Distanz = v_x t = v_0 cos(22.5°) t = 24m
*falsch, Folgefehler der Zeit*
