(b) 1 kgm/s
(c) 1 kgm/s²
(d) 1 kg/m²/s²
(e) 1 m/(kg-s²)

same height in a vacuum. Their velocities, on reaching the end of their fall are
equal because
(a)
(b)
(c)
(d)
(e)
the velocity of anything falling in a vacuum is constant
all objects reach the same terminal velocity when dropped from great heights
the acceleration due to gravity of the larger object is three times the
acceleration due to gravity of the smaller object
the force of gravity acting on both objects is the same
the acceleration due to gravity for both objects is the same
