imagine that two balls, a basketball and a much larger exercise ball, are dropped from a parking garage. If both the mass and radius of the exercise ball are 3 times larger than the mass and radius of the basketball, which of the two balls do you think will reach the ground first? Make a hypothesis below and describe your reasoning.

Hypothesis

Let there is no air drag or any other resistance force due to surrounding

Now the force equation of ball is given as

[tex]F = mg[/tex]

[tex]ma = mg[/tex]

[tex]a = g[/tex]

so the ball will be dropped down by acceleration a = g and this acceleration is independent of size and mass of the ball

So in this case both balls will be dropped by same acceleration.

So here both balls will hit the ground at same time
