Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 18 m/s at an angle θ = 28.5° above horizontal. Assume the water acts as a projectile that moves without air resistance.
a. Using v0, θ, 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 fireman place the hose for the water to reach its maximum height as it strikes the building? Express this distance, d, in expression in terms of v0, θ, and g.
Given:
Initial velocity of water is making an angle above the horizontal.
Water acts as a projectile.
Note:
Find:
(a) Write expression for time , when water reaches its maximum vertical height.
(b) The horizontal distance covered by water in terms of , and .
