The maximum height reached by the water before it starts coming back down is 40 m.

Maximum height reached by the water</h3>
The maximum height reached by the water before it starts coming back down is calculated by applying the principle of conservation of energy.
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = (v²)/(2g)
h = (28²)/(2 x 9.8)
h = 40 m

The photosynthesis equation is :
H2O + CO2 + sunlight (energy) > C6H12O6 + O2
So water (H2O) and carbon dioxide (CO2) are the raw materials need for photosynthesis.
The result of the Sun's light being refracted when it is
high in the sky around noon is blue, indigo and violet are strongly bent that
mostly skim through the upper atmosphere making the sky appear blue. The
refraction of the light during noon makes the sky blue.
Answer:
The velocity of ball is 23.19 m/s
Explanation:
Given that,
Mass of football player = 80.0 kg
Mass of ball = 0.430 kg
Distance = 0.538
We need to calculate the time
Using equation of motion
We need to calculate the velocity
Using formula of velocity
We need to calculate the velocity of ball
Using conservation of momentum
Put the value into the formula
The velocity of ball is 23.19 m/s
