V=g t

On Earth

V=10 t

The rock falls a distance d=5.0 m/s (1.0s) =5.0 m after falling 1.0 second

The rock falls a distance d=10.0 m/s (2.0s) =20.0 m after falling 2.0 seconds

The rock falls a distance d=15.0 m/s (3.0s) =45.0 m after falling 3.0 seconds

The rock falls a distance d=? after falling 4.0 seconds

The rock falls a distance d=20.0 m/s (4.0s) =80.0 m after falling 4.0 seconds
