On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snohomish River below. The swimmer's stepped off the bridge, and I estimated that they hit the water 2.00 s letter. How high was the bridge?

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
