1) Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 21.5 m/s at an angle θ = 29° 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. Part (a) Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. Part (b) At what horizontal distance...

Water from a fire hose is directed toward a building as shown in the figure below. The water leaves the hose at a speed of vi = 40.0 m/s and at an angle of θi = 47.0° above the horizontal. The base of the hose (at ground level) is a horizontal distance d = 55.0 m away from the building. Find the height h (in m) where the water strikes the building. .
