Answer:

h = 23.716 m

Step-by-step explanation:

Given that,

The time taken by the stone to hit the water is, t = 2.2 s

Height of the bridge above the ground, h = ?

The distance that the body will fall through the time is given by the formula

S = 1/2 gt² m

Where,

g - acceleration due to gravity

Substituting the values in the above equation

S = 1/2 x 9.8 m/s² x (2.2 s)²

= 23.716 m

Therefore, the height of the bridge from the surface of the water is h = 23.716 m
