Water leaves a Firemans hose (held near the ground) With an initial velocity vo=20.5 m/s at an angle theta= 31 degrees above horizontal. I assume the water acts as a projectile that moves without air resistance. Use a Cartisian coordinate system with the origin at the hose nozzle position. (A) using vo, theta, and g, write an expression for the time, tmax, The water travels to reach its maximum vertical height. (B) at what horizontal distance d From the building base, where should the firemen place the holes for the water to reach its maximum height as it strikes the building? Expressed a distance, D, in terms of vo, theta, and g.
