Answer to Question #5103 in Mechanics | Relativity for Ariana Steel
A fire hose ejects a stream of water at an angle of 30.3° above the horizontal. The water leaves the nozzle with a speed of 20.0 m/s. Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire?
a= 30 - angle v=20 m/s t- time when one projectile of water will rich middle of trajectory v*sina= gt t=20*0.5/10= 1sec
