Question: Free Fall Object dropped V y0 =0 m/s A y always -9.8 m/s 2 (- 10 m/s 2 for some instructors) Object thrown down some

Free Fall

  • Object dropped Vy0=0 m/s
  • Ay always -9.8 m/s2 (- 10 m/s2 for some instructors)
  • Object thrown down some initial velocity same acceleration (-9.8 m/s2)
  • Object thrown up: some initial velocity (Vy0), acceleration: -9.8 m/s2, velocity attop of flight is0 m/s
  • Time to goup to max height isequal to time to comedown from it.
