Awater hose can spray water at an
initial velocity of 40 feet per second. use the formula
h(t) = vnt - 16t-, where h(t) is the height of the water
in feet, v, is the initial velocity in feet per second, and
t is the time in seconds.

a. how long will it take the water to hit the
nozzle on the way down?

b. assuming the nozzle is 5 feet up, what is
the maximum height of the water?
