A water hose is used to fill a large cylindrical storage tank of diameter D and height 2D . The hose shoots the water at 45 ∘ above the horizontal from the same level as the base of the tank and is a distance 6D away.
For what range of launch speeds (v0) will the water enter the tank? Ignore air resistance, and express your answer in terms of D and g .Homework Equations
Vx=Vt
D=vit+1/2at^2
The Attempt at a Solution
I tried plugging in the values into theequation and I end up with√6dG<V<√√7dG

Clever student's strategy: Unless the problem states a condition explicitly, choose the simplest situation to work with and declare it as an assumption. Just make sure that it's really undefined and not subtly implied somehow in the problem statement.[USER=569844]@navin[/USER] said:

The water flows in a parabolic path, similar to the path of a projectile. This is due to the force of gravity acting on the water, causing it to follow a curved trajectory.
The range of a water hose in projectile motion is affected by the initial velocity, angle of launch, and air resistance. These factors can increase or decrease the range of the water hose.
Yes, the range of a water hose can be calculated using the projectile motion equations, as long as the initial velocity, angle of launch, and air resistance are known.
If the angle of launch is increased, the range of the water hose will also increase. This is because a higher angle will result in a higher initial velocity, which will cause the water to travel further before hitting the ground.
Air resistance does play a role in the trajectory of a water hose, but it is not a significant factor. This is because the mass and velocity of the water droplets are relatively low compared to other projectiles, and therefore air resistance has a minimal effect on their trajectory.
