Answer:

7.827s

Explanation:

Given that

Height of the Eiffel tower is (h) =300.5m

Acceleration due to gravity (g) =9.81m/s2

From the kinematic equations

s =ut+(1/2)gt2

It is free fall then u =0

Then h =(1/2)gt2

Then the time taken for the croissant dropped before it tagged you on the head. is t =Sqrt(2h/g) =Sqrt(2*300.5/9.81)=7.827s
