Answer:

It will take him 3.29 s to reach his aquatic homeland

Step-by-step explanation:

From the equation of motion,

S = ut + 1/2gt² .................... Equation 1

Where S = Height, u = initial velocity, g = acceleration due to gravity, t = time.

Note: For a falling body, u = 0 m/s.

S = 1/2gt²...................... Equation 2

Making t the subject of the equation

t = √(2S/g)...................... Equation 3

Given: S = 53.0 m,

Constant: g= 9.8 m/s²

Substituting these value into equation 3

t = √(2×53/9.8)

t = √(106/9.8)

t = √10.82

t = 3.29 s

Therefore it will take him 3.29 s to reach his aquatic homeland
