Answer:

Velocity = 94.85m/s

Explanation:

Given the following data ;

Height = 1200m

Vertical distance = 1050m

To find the time, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting into the equation, we have;

[tex] 1200 = 0(t) + \frac {1}{2}*9.8*t^{2}[/tex]

[tex] 1200 = 0 + 4.9*t^{2} [/tex]

[tex] 1200 = 4.9*t^{2} [/tex]

[tex] t^{2} = \frac {1200}{4.9} [/tex]

[tex] t = \sqrt{122.45}[/tex]

t = 11.07 secs

To find the velocity;

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

Substituting into the above equation;

[tex]Velocity = \frac{1050}{11.07}[/tex]

Velocity = 94.85m/s

Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.
