Question

P 31
A fire hose held near the ground shots water at a speed of6.5m/s. At what angle(s) should the nozzle point in order that thewater land 2.5m away Why are there two different angles? Sketch thetwo trajectories.
(the water is assumed to start at a horizontal position ofzero.)
im just very confused.

Explanation / Answer

   the range is given by    R = vo2 sin(2 /g)    2.5 m = (6.5 m / s)2 sin(2/ g)    sin2 = ......    2 = .......o and.....o    the required angles will be 90 -.....o    the required angles will be 90 -.....o
