Question

A) Using vo, O, and g, write an expression for the time, Imax, the water travels to reach its maximum vertical height.

tmax=

 

Part (b) At what horizontal distance d from the building base, where should the fireman place the hose for the water to reach its maximum height as it strikes the building? Express this distance, d, in terms of Va. O, and g.

d=

7: Water leaves a fireman's hose (held near the ground) with an initial velocity vo =
14.5 m/s at an angle = 27° above horizontal. Assume the water acts as a projectile that moves without
air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position, as shown.
