China is completing the construction of the tallest bridge in the world, which runs through the Grand Huajiang Canyon. The 2,890-meter-long steel suspension bridge rises 625 meters above sea level

You're supposed to show your work. Haha.

[u/Ruskih → u/ScramJetMacky]

d = 1/2 gt²

d= distance(625m) g=gravity(9.8m/s²⁾
t=time

2d = gt²

2d/g = r²

t = √2d/g

t = √[2(625)/9.8]

t = 11.29

Don't forget air resistance!

If my physics book can ignore air resistance, so can he.
