Final answer:
The student's question involves calculating the angle for a nozzle so water reaches a certain distance, utilizing principles of projectile motion in physics.
Step-by-step explanation:
The question refers to the application of physics, particularly projectile motion, to determine the angle at which a nozzle of a garden hose should be pointed to ensure water lands at a particular distance. Using initial velocity, gravitational acceleration, and the distance to be covered, we can calculate the required angles.
