Final answer:

The force of the spray is found by multiplying the pressure of the spray by the area covered. With a pressure of 75 psi and an area of 0.442 square inches, the force is calculated to be 33.15 pounds.

Step-by-step explanation:

To solve for the force of the hose spray, we can use the definition of pressure, which is force per unit area. The formula to find force (F) is:

F = Pressure × Area

We are given a pressure of 75 pounds per square inch (psi) and an area of 0.442 square inch. Plugging these values into the formula, we get:

F = 75 psi × 0.442 in² = 33.15 pounds

Therefore, the force of the spray is 33.15 pounds.
