A girl is walking across a bridge and drops her lipstick. It the bridge is 35 m high, how long will it take to hit the ground?

Question

i need help

Answer 1

If there is no air resistance, set the height of the bridge equal to gt²/2 and solve for t.

 

h = gt²/2

 

h = 35 m

g = 9.8 m/s²

 

Plug in the numbers and solve for t.
