Unformatted text preview: d) When the ball is at x = x f , what is the vertical coordinate in terms of x f , v and ? e) When the ball is at x = x wall , what is the vertical coordinate in terms of x wall , v and ? f) Turn this page over and solve the equations for in terms of h , x wall and x f . (you may want to try this on a separate sheet of paper first, as this is quite difficult) f) continued 2. [8 pts] A fireman holds a fire hose at angle from the horizontal, aiming it at a building across the street. If the water leaves the nozzle at speed v , and the width of the street is w , at what height h does the water hit the building? You may neglect the height of the fireman. a) How long does it take ( t ) for water to travel from the nozzle to the building? b) At what height h does the water hit the building, in terms of , v , w and g ?...
