If a baseball, a basketball, and a 71.2 n shot were dropped simultaneously from the top of the empire state building (and air resistance was not a factor), which would hit the ground first?

The objects will reach the ground at the same time

Explanation:

m = Mass of object

a = Acceleration

m = Mass of the Earth =  5.972 × 10²⁴ kg

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

R = Radius of Earth = 6371000 m

The weight of an object balances the gravitational force

The mass of the of any object gets cancelled

All objects irrespective of their weight will fall with the acceleration equal to 9.81364 m/s².

So, here the baseball, basketball, and the 71.2 N shot will hit the ground at almost the same time. There will be little variation due to the surface area of each body but will mostly reach the ground at the same time.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
