(3%) Problem 19: Water leaves a fireman's hose (held near the ground) with an initial velocity vo= 11.5 m/s at an angle = 29.5 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. ng this I 50% Part (a) Using vo, 6, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. d 'max= ed cos(a) cos(Q) cos(0) () 7 8 9 HOME sin(a) sin(Q) sin(0) 1 4 56 1 2 3 d g h + 0 m t VO VO BACKSPACE END CLEAR Hint Feedback I give up!
