Question

in the diagram, the hose is held straight up at theta degrees going at 6.5 m/s and with water falling down.. the distance between initial and final water displacement is 2m.. a fire hose held near the ground shoots water at a speed of 6.5 m/s. at what angle(s) should the nozle point in order that the water land 2.0 m away, why are there two different angles?

Answer 1

The range of a projectile is given by the formula:
R = (v²sin(2∅))/g
2 = 6.5² x sin(2∅) / 9.81
∅ = 13.8°
