A 10 g dime and a 200 g gold coin are dropped from the Empire State Building in New York at the same time.; if there is no air resistance which hits the ground first?

A. They both hit the ground at the same time

B. Which hits first depends on the weather & temperature of the air.

C. The 200 g gold coin hits the ground first

D. The 10 g dime hits the ground first

Explanation:

The both hit the ground at the same time. There is no air resistance and that includes the factors brought up in B.

C and D are both eliminated. If you dropped an 800 kg honda Fit it would hit the ground at the same time as the two coins. When you look at the formulas used to derive time, they look like

d = vi * t + 1/2 a* t^2

vi = 0

the distance to fell is the same for all three masses.

a is the same for all 3 masses.

So when you solve for t, there is no mention of the mass of the object falling. Therefore t is dependent only on the height.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
