Answer:
Step-by-step explanation:
Projectile Motion
When an object is launched with an initial velocity and angle above the horizontal, it describes a curve called a parabola, with a vertex in the point where the object has its maximum height and then it finally returns to the ground level.
The water is to be shot to a fixed height from a horizontal distance to be determined. Please refer to the figure below. There are two possible solutions to the problem: the first when the water is still moving upwards, and the second when it has already reached the maximum height and is going downwards. The distances are called d1 and d2.
The height of an object launched at vo and \theta is

And the horizontal distance it reaches can be computed by

Let's solve it for t as follows

And replace it on the previous equation

Simplifying and rearranging, we have the equation that relates both components of the combined motion

Plugging in the given values

We have

Rearranging

We have to solve the second-degree equation

There are two feasible solutions:
