They hit at the same time. Everything falls at the same rate.
Answer:
All arrive at the same time on the ground.
Explanation:
For this exercise let's use Newton's second law
F = m a
The force is the attraction of gravity of the Earth on the body
F = W = mg
Let's replace
m g = m a
a = g
We can see that the acceleration of the body is independent of its masses, so that the three bodies, bowling, tennis and pen have the same acceleration and as the three legs of rest. All arrive at the same time on the ground.
