A 1 kg ball and a 10 kg ball are dropped from a height of 10 m at the same time. In the absence of air resistance,

(A) the two balls will hit the ground at the same time.
(B) the 1 kg ball will hit the ground first.
(C) the 10 kg ball will hit the ground first.
(D) the 10 kg ball will take 10 times the amount of time to reach the ground.
(E) there is not enough information to determine which ball will hit the ground first.

A

Explanation: Neglecting air resistance every object will return to the ground at the same interval regardless of their weights, we can say that the objects are undergoing free falls, they are falling under the sole of gravity.

No matter the weight of the objects or the elevation, without significant air resistance, they will 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
