Answer:
19.62 m
Explanation:
t = Time taken = 2 s
u = Initial velocity = 0
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
It is assumed that the people are in free fall
From Equation of linear motion
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
[tex]\Rightarrow s=0\times 2+\dfrac{1}{2}\times 9.81\times 2^2[/tex]
[tex]\Rightarrow s=19.62\ m[/tex]
The height of the bridge is 19.62 m
