the acceleration of gravity on the surface of venus is 8.9 m/s2. would a ball thrown upward from venus return to the ground sooner or later than a ball thrown upward with the same speed on the earth?

1 answer

downward motion
H=gt²/2
t=sqrt(2H/g)
Time↑= time↓ =>
Total time = 2 •sqrt(2H/g).
Since g(Venus)<g(Earth) ,
t(Venus)>t((Earth)
