Answer:
<em>The water hits the wall at a height of 5.38 m</em>
Explanation:
<u>Projectile Motion </u>
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
The object describes a parabolic path given by the equation:
Where:
y = vertical displacement
x = horizontal displacement
θ = Elevation angle
vo = Initial speed
The hose projects a water current upwards at an angle of θ=40° at a speed vo=20 m/s.
The height at which the water hits a wall located at x=8 m from the hose is:
Calculating:
y = 5.38 m
The water hits the wall at a height of 5.38 m
