The acceleration of gravity on the surface of Venus is 8.9 m/s2. Would a ball thrown upward on Venus return to the ground sooner or later than a ball thrown upward with the same speed on the earth?
Time of the flight to the top point where v=0 is
v = vₒ - gt => 0= vₒ - gt,
The large “g” the smaller “t”.
Since the time upward = time downwards,
the time of the flight at the Earth is smaller than the time at the Venus.
